	* session.scm: Use module (ice-9 regex).
	(help): Regexp-quote a name given as a symbol.

2000-06-16  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* common-list.scm (list*):  Removed, since this function is
	implemented as a primitive in libguile/list.c.

2000-06-12  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>

	* session.scm (help): Warn user if 'regex isn't provided.

	* Makefile.am (ice9_sources): Removed getopt-gnu-style.scm.

	* getopt-gnu-style.scm: Removed deprecated module.

2000-06-11  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>

	* boot-9.scm (make-autoload-interface): Set init value for uses to
	'() instead of #f.
	(make-modules-in): Name modules with their real (= full) names.
	(the-root-module, the-scm-module): Named `(guile)' instead of
	`the-root-module'.
	(the-scm-module): Set kind to 'interface.

	* Makefile.am (ice9_sources): Replaced doc.scm with
	documentation.scm.

	* session.scm (ice-9): Use module (ice-9 documentation).
	(name): Use the name property if everything else fails.
	(apropos-fold): New procedure.
	(apropos-internal): Re-implement in terms of `apropos-fold'.
	(help): Rewritten.

	* doc.scm: Removed module (ice-9 doc).

	* documentation.scm: New module (ice-9 documentation).

2000-06-08  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>

	* doc.scm (documentation-files): Renamed from `doc-files'.
	(write-all): Removed.
	(find-documentation): Renamed from `documentation'.  Return
	documentation string instead of printing it.  Not exported.

2000-06-05  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>

	* boot-9.scm (error-catching-loop): Inform about debugger on error.

2000-06-04  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>

	* boot-9.scm (scm-module-closure): New procedure: Was previously
	anonymous.  Now needed in modules.c.
	(make-module): Use `standard-eval-closure' to create the eval
	closure.

2000-05-14  Gary Houston  <ghouston@arglist.com>

	* boot-9.scm (load-user-init): rewritten.  first work out the home
	directory and then try to open the file (previously it could try
	to open a file in more than one place).  catch exceptions when
	trying to get a directory from the user database.  don't check
	that ~/.guile is not a directory before trying to load it (a lack
	of ~/.guile is not a crime, but if the file is not valid for any
	reason then primitive-load will raise an error).

2000-05-11  Dirk Herrmann  <D.Herrmann@tu-bs.de>

	* boot-9.scm (abs):  Don't set to magnitude.  abs now does not
	accept complex numbers as parameter.

2000-05-09  Marius Vollmer  <mvo@zagadka.ping.de>

	* common-list.scm (delete-if-not!): Bug fix of bug fix: change
	label of named let to `delete-if-not'.  Sorry.

2000-05-08  Marius Vollmer  <mvo@zagadka.ping.de>

	* common-list.scm (doc fixes): Talk about `true values' instead of
	`#t' when a function treats all non-#f valuers the same.
	(remove-if-not): Bug fix: call remove-if-not
	instead of remove-if when iterating.
	(delete-if-not!): Bug fix: call delete-if-not! instead of
	delete-if! when iterating.

2000-04-16  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>

	* r4rs.scm (close-input-port, close-output-port): Removed.

2000-04-13  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>

	* session.scm (help): New macro.  Prints helpful information.

2000-04-10  Gary Houston  <ghouston@arglist.com>

	* popen.scm (open-process): after forking, close all ports except
	the end of the pipe to the parent.  otherwise move->fdes and
	the exec'd program and the exit handlers can interfere with file
	descriptors still in use in parent ports.

2000-04-09  Gary Houston  <ghouston@arglist.com>

	* popen.scm (close-process-quietly): new procedure.  use it from
	reap-pipes to avoid errors or hanging during background cleanup.

2000-04-04  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>

	* format.scm (format:obj->str): Handle circular references.  Also,
	print improper lists with (x y . z) syntax rather than as
	individual pairs.  (This code should probably be integrated into C
	level facilities.  It is currently terribly slow.)

2000-04-03  Michael Livshin  <mlivshin@bigfoot.com>

	* streams.scm (stream-fold, stream-for-each): don't use named let, 
	because it prevents the gc from junking the stream argument.

Thu Mar  9 08:05:08 2000  Greg J. Badros  <gjb@cs.washington.edu>

	* slib.scm: Back-out change to software-type -- renamed
	slib:software-type to software-type, and leave it non-public.

Thu Mar  2 12:20:52 2000  Greg J. Badros  <gjb@cs.washington.edu>

	* boot-9.scm: Drop unused definition of sfx function -- thanks
	Dirk Hermann!

Wed Mar  1 12:21:02 2000  Greg J. Badros  <gjb@cs.washington.edu>

	* streams.scm: Doc patch from Richard Kim, using MIT Scheme as
	source of the numerous very short changes.

Sun Feb 13 18:03:19 2000  Greg J. Badros  <gjb@cs.washington.edu>

	* slib.scm: Rename software-type to slib:software-type and make it 
	public.

	* r4rs.scm: Added documentation; largely cut and pasted from R4RS
	info pages.

Sun Feb 13 17:49:29 2000  Greg J. Badros  <gjb@cs.washington.edu>

	* common-list.scm: Added documentation; largely cut and pasted
	from slib docs.

2000-02-11  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>

	* format.scm (format): Reintroduce (define format format:format)
	so that the binding in the public interface of the module will be OK.

2000-01-30  Gary Houston  <ghouston@arglist.com>

	* boot-9.scm (find-and-link-dynamic-module): pass strings, not symbols,
	to string-append.

2000-01-29  Gary Houston  <ghouston@arglist.com>

	* expect.scm (expect): don't call char-ready? before expect-select,
	since select now checks port buffers itself.  don't bother to check
	the time first either, since expect-select does it.

Thu Jan 20 12:57:36 2000  Greg J. Badros  <gjb@cs.washington.edu>

	* format.scm: Use (variable-set! (builtin-variable 'format)) to
	re-define format to be format:format (instead of just define,
	which interacts poorly with the module system).  Thanks to Shuji
	Narazaki for this change.

Tue Jan 11 10:49:22 2000  Greg J. Badros  <gjb@cs.washington.edu>

	* boot-9.scm expect.scm, syncase.scm: Switch to new style
 	`simple-format' message strings: substitute ~A for %s, and ~S for
 	%S.

	* boot-9.scm:  Added (define format simple-format) to expose that
	primitive via the simpler name until format.scm is loaded.

2000-01-09  Marius Vollmer  <mvo@zagadka.ping.de>

	* boot-9.scm (try-using-libtool-name): Do not bother to look
	inside libtool ".la" file, dynamic-link does this for us now.

1999-12-15  Gary Houston  <ghouston@freewire.co.uk>

	* slib.scm (library-vicinity, home-vicinity, 
	scheme-implementation-type, scheme-implemenation-version):
	use define-public to export from the module.

Wed Dec 15 08:32:09 1999  Greg J. Badros  <gjb@cs.washington.edu>

	* doc.scm: Use `%library-dir' and the other system directories,
 	not the quickly defuncted `library-dir' that I added before
 	realizing the former existed.  Thanks Brad Knotwell!

Sun Dec 12 19:18:52 1999  Greg J. Badros  <gjb@cs.washington.edu>

	* Makefile.am, doc.scm: Added doc.scm.

1999-12-12 18:54:06 1999  Greg J. Badros  <gjb@cs.washington.edu>

	* popen.scm, slib.scm: Added some docstrings for procedures that
	were primitives that I encountered in posix.texi.
	
1999-11-19  Gary Houston  <ghouston@freewire.co.uk>

	* Makefile.am (ice9_sources): add arrays.scm.

	* boot-9.scm: load arrays.scm if 'array is provided.

	* arrays.scm: new file with stuff from boot-9.scm.

1999-11-18  Gary Houston  <ghouston@freewire.co.uk>

	* boot-9.scm (read-hash-extend to set up arrays): add 'l' for
	long_long uniform vectors.

1999-11-17  Gary Houston  <ghouston@freewire.co.uk>

	* networking.scm (sethostent, setnetent, setprotoent, setservent):
	take an optional argument STAYOPEN.  default is #f.

1999-10-05  Jim Blandy  <jimb@savonarola.red-bean.com>

	* Makefile.in: Deleted from CVS repository.  Run the autogen.sh
	script to create generated files like this one.

1999-09-23  Gary Houston  <ghouston@freewire.co.uk>

	* boot-9.scm (load-user-init): check that the posix feature is
	available before using getpw and getuid.
	(top-repl): don't install handlers for SIGINT etc., without posix.
	(file-is-directory?): use 'posix instead of i/o-extensions to 
	check for stat.
	(load-user-init): use file-exists? and file-is-directory? to
	check for .guile, instead of stat.
	(file-is-directory?): don't display the file name if posix not
	available.
	(feature?): I guess this is deprecated.  redefined using "provided?"
	and changed users in boot-9.scm to "provided?".
	Conditionally load posix.scm and networking.scm.

	posix.scm, networking.scm: new files.  Move definitions from
	boot-9.scm if they are only useful with posix/networking available.
	
	* Makefile.am (ice9_sources): add posix.scm, networking.scm.

1999-09-17  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>

	* debugger.scm (read-and-dispatch-commands): Handle other throws
	than 'exit-debugger.

	* boot-9.scm (before-signal-stack): New fluid.
	(top-repl): Set before-signal-stack in the signal handler.

	* debugger.scm (eval-handler): Handle unhandled exceptions.

1999-09-16  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>

	* debugger.scm ("p"): New alias for "evaluate";
	Mark module with :no-backtrace.
	("position"): New command.
	(source-position, display-position): New procedures.
	(display-source): Display position of expression, if available.
	(catch-user-errors): Return #f on error.  (Commands are expected

	(read-and-dispatch-command): Bugfix: Return old state on error.

1999-09-16  Jim Blandy  <jimb@savonarola.red-bean.com>

	* regex.scm (regexp-substitute/global): Handle the end of the
	match list and an empty match list identically.  (Thanks to Greg
	Badros.)

1999-09-15  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>

	* debugger.scm ("evaluate"): Replaced `write-line' with calls to
	`write' and `newline' since write-line doesn't write but displays.

1999-09-12  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>

	* debugger.scm ("evaluate"): Newline after no env announcement.

	* debug.scm, emacs.scm: Updated copyright notices.

	* boot-9.scm (make-autoload-interface): Bugfix.
	(top-repl): Autoload debugger.

	* debugger.scm ("backtrace"): Don't pass length param to
	display-backtrace if it wasn't explicitly given by the user.
	(write-frame-long/application): Also print corresponding source
	expression.
	("evaluate"): Evaluate in local environment frame, if existent;
	Handle errors.

1999-09-11  Jim Blandy  <jimb@savonarola.red-bean.com>

	* format.scm (format:format-work): Use #\tab and #\page instead of
	slib:form-feed and slib:tab.  (Thanks to Ceri Storey.)

	* format.scm (format:abort): Call error, not slib:error.

1999-09-11  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>

	* boot-9.scm (using-readline?): New procedure: Returns #t if
	readline is used by the repl run by this thread.
	(handle-system-error): Print "Backtrace:" before backtrace since
	this is no longer done by display-backtrace.
	
	* debug.scm (frame-number->index): Optionally take stack as
	argument.

	* debugger.scm: Use the frame number abstraction which allows for
	both forward and backward views of the stack

	Use selector `frame-number';
	(select-frame-absolute): Use frame-number->index.
	("backtrace"): Use builtin backtrace printing.

	list-matches, to get null match behavior correct.

	* regex.scm (regexp-substitute/global): Rewrite so that 'post at
	the end of the item list actually causes a tail call.  (Thanks to
	Jan Nieuwenhuizen.)

1999-09-11  Marius Vollmer  <mvo@zagadka.ping.de>

	* readline.scm: Moved to ../guile-readline.

	* boot-9.scm (top-repl): Removed code for activating readline.

	* Makefile.am: Removed mention of readline.scm.

	* Makefile.in: Regenerated.
	
1999-09-11  Jim Blandy  <jimb@savonarola.red-bean.com>

	Delete the test which compares the configuration date of libguile
	with the configuration date of ice-9.  This test yields too many
	false positives to be helpful.  For example, if you build Guile
	for several architectures but have them all share a "share"
	directory (which is supposed to work), then all but one
	architecture's Guile will complain that the configuration dates
	don't match.  Which is true, but indicates nothing wrong.
	* boot-9.scm: Delete code which compares ice-9-config-stamp with
	libguile-config-stamp.
	* version.scm.in: Delete.
	* Makefile.am (ice9_generated): Delete.
	(subpkgdata_DATA): Remove ice9_generated.
	(EXTRA_DIST): Remove version.scm.in.
	* Makefile.in: Regenerate.

1999-09-11  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>

	* debugger.scm: New file: Initial version of the Guile debugger
	written by Chris Hanson.  (The debugger isn't finished, but is
	included in Guile anyway since it is already quite useful.)

	* boot-9.scm (top-repl): Use (ice-9 debug) (ice-9 debugger) (ice-9
	session) (ice-9 threads) (ice-9 regex) from guile-user only if
	top-repl is called.  This makes startup time for scripts 30% of
	what it was before...  Removed redundant code for loading of
	readline.

	* Makefile.am (ice9_sources): Added debugger.scm.

1999-08-29  Keisuke Nishida  <kxn30@po.cwru.edu>

	* boot-9.scm (try-module-autoload): Use %search-load-path.
	
1999-08-24  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>

	* boot-9.scm: Removed old style hooks.
	(inherit-print-state): Rwwritten to use port-with-print-state.

1999-08-20  James Blandy  <jimb@mule.m17n.org>

	Remove support for the #/ path list syntax entirely.
	* boot-9.scm (read-path-list-notation,
	read-path-list-notation-warning): Deleted.
	Don't register read-path-list-notation-warning as a reader for
	objects starting with '#/'.

1999-08-05  Mikael Djurfeldt  <mdj@thalamus.nada.kth.se>

	GOOPS needs the observer protocol specified for the new module
	system.  Here's a simple version for the old module system:
	* boot-9.scm (module-observers, module-weak-observers,
	module-observer-id, set-module-observers!,
	set-module-observer-id!): New accessors.
	(module-type): Added slots `observers',	`weak-observers' and
	`observer-id'.
	(module-observe, module-observe-weak, module-unobserve,
	module-modified): New procedures.
	(module-make-local-var!, module-add!, module-remove!,
	module-clear!, module-define!, module-use!): Call module-modified.

1999-07-29  Marius Vollmer  <mvo@zagadka.ping.de>

	* boot-9.scm (error-catching-loop): Correct non-RnRS usage of internal
	defines.

1999-07-19  Jim Blandy  <jimb@savonarola.red-bean.com>

	* streams.scm: New module, contributed by Michael Livshin.
	* Makefile.am (ice9_sources): List it.
	* Makefile.in: Regenerated.

	* boot-9.scm (read-delimited!): Put the terminator in the correct
	position.

1999-06-29  Mikael Djurfeldt  <mdj@mdj-pc.nada.kth.se>

	* readline.scm: Bugfix: Avoid getting the continued-lines prompt
	at multiple calls to read.
	(promtp2): Variable for continued-lines prompt.
	(make-readline-port): Use prompt2.
	(set-readline-prompt!): New optional arg which sets
	continued-lines prompt.

	* boot-9.scm (top-repl): Set/clear readline prompts before/after
	reading expressions.

1999-06-18  Jim Blandy  <jimb@savonarola.red-bean.com>

	* ls.scm (ls, lls): Handle no arguments as meaning to look in
	`(current-module)'. (Patch from Thien-Thi Nguyen.)

1999-06-14  Jim Blandy  <jimb@savonarola.red-bean.com>

	* string-fun.scm (split-before-predicate, split-after-predicate,
	split-discarding-predicate): Make these public.  (Thanks to
	Thien-Thi Nguyen.)

	1999-06-13  Gary Houston  <ghouston@easynet.co.uk>

	* more changes to expect.scm, to avoid the one-character lookhead
	that was introduced to fix the $ problem:

	* expect.scm (expect): call the match proc an extra time at end
	of file and set the eof? argument appropriately.  call 
	expect-eof-proc only if the last call didn't match.
	* expect.scm (expect-strings): change port to eof? in match proc.
	* expect.scm (expect-regexec): take an eof indicator as an argument
	instead of a port.

1999-06-09  Jim Blandy	<jimb@savonarola.red-bean.com>

	* Makefile.am (ice9_sources): Add popen.scm to list.
	* Makefile.in: Regenerated.

	Fixes for expect from Gary Houston  <ghouston@easynet.co.uk>:

	* expect.scm (expect-regexec): define 'eof-next?'.  I don't
	know why it was missing.  also don't peek for end of lines
	unless expect-strings-exec-flags contains regexp/noteol.
	(expect-strings-exec-flags): initialise to regexp/noteol.

	Gary Houston's open-buffer port patches:

	1999-04-01  Gary Houston  <ghouston@easynet.co.uk>

	* popen.scm: applied fixes from Greg Harvey.  use a guardian
	and a gc-thunk so that cleanup is done if a pipe is garbage
	collected or closed with close-port.  use a weak hash-table instead of 
	an alist.
	
	1999-03-20  Gary Houston  <ghouston@easynet.co.uk>

	* expect.scm (expect): call the match proc with the port instead.
	(expect-strings): use peek-char to get the next char.  this has
	the advantage of getting the handling of $ "correct", but the
	disadvantage of needing to get (and maybe block for) an extra character
	from the port when it may not be needed.  hence:
	(expect-strings-exec-flags): new variable/parameter, supplies
	flags for regexp-exec.	if this includes regexp/noteol, then
	automatic regexp/noteol handling (requiring an extra peeked char) 
	is enabled.  default is regexp/noteol.
	(expect-strings-compile-flags): new variable/parameter, supplies
	flags for make-regexp.	default is regexp/newline.

	1999-03-15  Gary Houston  <ghouston@easynet.co.uk>

	* expect.scm (expect): call the match proc with an extra char,
	peeked from the stream.
	(expect-strings): build a match proc which takes the extra char.
	(expect-regexec): take an extra arg "eof-next?" and use it
	to decide whether the regexp/noteol flag should be added.

	1999-02-26  Gary Houston  <ghouston@easynet.co.uk>

	* boot-9.scm (top-repl): don't flush all ports at exit.
	(error-catching-loop): likewise.

	1998-12-23  Gary Houston  <ghouston@easynet.co.uk>

	* boot-9.scm (scm-style-repl): -read: don't call
	consume-trailing-whitespace if val is eof object.  Allows
	exiting repl with single control-D.

	1998-12-06  Gary Houston  <ghouston@easynet.co.uk>

	* boot-9.scm (error-catching-loop): don't force output within
	error catching loop after quit received.
	(top-repl): flush all ports when the repl terminates.

	* boot-9.scm (error-catching-loop): flush all ports before 
	primitive exit if non-interactive. 
	force-output on current-error-port if interactive.

	* boot-9.scm (reopen-file): deleted.
	* popen.scm (open-output-pipe, open-input-pipe): moved from
	boot-9.scm.
	* popen.scm: new file.

1999-06-04  Dirk Herrmann  <D.Herrmann@tu-bs.de>

       * boot-9.scm (iota):  replaced by a tail recursive version.
       (reverse-iota):	removed.

1999-06-03  Mikael Djurfeldt  <mdj@mdj-pc.nada.kth.se>

	* optargs.scm (lambda*): Bugfix: Replaced ARGLIST -->
	non-optional-args.  (Thanks to David Lutterkort.)

1999-05-09  Jim Blandy	<jimb@savonarola.red-bean.com>

	* string-case.scm: Removed; functions moved to libguile/strop.c
	(which could be dynamically linked in the future anyway).
	* Makefile.am (ice9_sources): Don't list string-case.scm.
	* Makefile.in: Regenerated.
	* format.scm: Don't bother importing (ice-9 string-case).

1999-05-02  Jim Blandy	<jimb@savonarola.red-bean.com>

	* boot-9.scm (provided?): New function.

	* Makefile.am: Add string-case.scm and format.scm to ice9_sources.
	* Makefile.in: Regenerated.
	
	* string-case.scm: New file, brought in from SLIB, and adapted to
	Guile's module system.

	* format.scm: New file, brought in from SLIB, with the following
	changes:
	(format:format): If the first argument is the format string, stick
	a #f on the front of it, so it is now a valid CL format argument
	list.  This is easier than changing everyplace else (like the
	error formatter) that expects it to be in CL form.  The other
	clause which explicitly tests for this case is now dead code.
	(format:format-work): Allow `@' and `:' in either order, as per
	modern CL behavior.
	(format:num->cardinal): Don't assume that an elseless if returns
	'() when the condition is false.
 
1999-04-17  Jim Blandy	<jimb@savonarola.red-bean.com>

	* Makefile.in: Regenerated.

1999-04-08  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>

	* boot-9.scm: Provide 'values.

1999-03-21  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>

	* boot-9.scm (process-define-module, use-syntax): Bugfix:
	:use-syntax should add syntax to using module, not current module.
	(internal-use-syntax): Removed.

1999-03-21  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>

	* session.scm (apropos-internal): Modified to comply with new
	argument order for hash-fold.

1999-03-19  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>

	* boot-9.scm (try-load-module): New procedure.	Broken out from
	resolve-module.
	(resolve-module): Bugfix: Make it possible for a module at a
	deeper level (x y z) to depend on a module on a higher (x y).

	This also has the desired side-effect that multiple attempts to
	load a module (e.g. with `use-modules') work until source is
	actually found for the module (e.g. because the correct catalog
	has been added to the load path).
	
	Use try-load-module.

1999-03-18  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>

	* session.scm (system-module): New procedure.  Used to switch a
	module between system and user state.

1999-03-16  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>

	* session.scm (apropos-internal): Rewritten using hash-fold.

	* emacs.scm, session.scm, slib.scm): Added :no-backtrace in module
	definition.

1999-03-14  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>

	* boot-9.scm (make-record-type): Use `set-struct-vtable-name!' to
	associate a name to the record type descriptor so that the object
	system can create a wrapper class for it.

1999-03-12  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>

	Improvement of backtraces: Introduces a new stack narrowing
	specifier, #t, for the inner cut.  If the inner cut is specified
	by #t, `make-stack' will throw away inner stack frames (most
	recent calls on call chain) up to but excluding the first user
	stack frame encountered.

	This specifier is now used in `save-stack' so that the call
	`(save-stack)' will get the new behaviour. [It is recommended that
	any error reporting functions written by the user have this call
	on the outermost expression level (i.e. as a member of the lambda
	list).]

	Modules are partitioned into "user" and "system" modules. [I know
	that some names used here are silly, but I don't have more time to
	spend on a better solution, especially considering that the module
	system will be replaced.  But if people have better ideas, then
	please tell me!]

	System modules are created by adding :no-backtrace among the
	define-module switches:

	(define-module (foo)
	  :no-backtrace)

	Modules which doesn't have the :no-backtrace specifier are user
	modules.
	
	A stack frame is classified as a user frame if it has source code
	associated with it and if this source code can be proven to come
	from a user module.  If it can be proven to come from a system
	module it is a system frame.

	Frames which can't be classified, e.g. application frames, are cut
	away if they occur between system frames, but are left on the
	stack if they occur between the last system frame and the first
	user frame encountered.	 (Note that the first user frame
	encountered is the last user code being evaluated!)

	In some cases the system part of the call chain is introduced by
	frames which should but can't be proven to be system frames.  The
	following workaround has been implemented: The cutting proceeds
	over application frames where the operator is marked by the
	`system-procedure' property.  (This has been used to cut away
	generic function dispatch code in the object system.)

	* boot-9.scm (set-system-module!): New procedure: Set system/user
	status of a module.;
	Mark `the-root-module' and `the-scm-module' as system modules.
	(process-define-module): Add new keyword :no-backtrace.

	* boot-9.scm (environment-module): Bugfixed.
	(set-module-eval-closure!): Add a pointer back from the eval
	closure to the module.

	* emacs.scm (emacs-load): Reset port filename after transfer.

1999-03-03  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>

	* slib.scm (make-random-state): Added for compatibility.

1999-02-16  Maciej Stachowiak  <mstachow@alum.mit.edu>

	* optargs.scm (lambda*): Handle empty argument lists properly.

1999-02-15  Jim Blandy	<jimb@savonarola.red-bean.com>

	Fix from Russ McManus:
	* getopt-long.scm (parse-option-spec): Store 'optional as the
	value-required? field for options that take optional values.
	(process-short-option): Grab a value for the option when it takes
	either an optional or required value.

1999-02-12  Jim Blandy	<jimb@savonarola.red-bean.com>

	* getopt-long.scm: Remove debugging calls to `pk'.

	* getopt-long.scm: Return list of ordinary arguments as the value
	of the '() key, not `rest'.

	A new argument-processing package from Russ McManus.
	* getopt-long.scm: New file.
	* Makefile.am (ice9_sources): Added getopt-long.scm.
	* Makefile.in: Regenerated.

1999-02-09  Maciej Stachowiak  <mstachow@alum.mit.edu>

	* optargs.scm: New file. 
	* Makefile.am (ice9_sources): Add optargs.scm here. Makefile.in
	not regenerated because I don't have the right version of Automake.

1999-02-06  Jim Blandy	<jimb@zwingli.cygnus.com>

	* and-let*.scm: New file, from Michael Livshin.
	* Makefile.am (ice9_sources): Add and-let* here.
	* Makefile.in: Regenerated.

1999-01-11  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>

	* slib.scm (install-require-module): Fixed the kludge which loads
	the slib catalog: Doesn't anylonger assume that the feature tested
	for isn't loaded.

1998-12-14  Jim Blandy	<jimb@zwingli.cygnus.com>

	* Makefile.in: Regenerated.

1998-12-14  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>

	* boot-9.scm (process-define-module): Reverted the change of
	1998-11-23 which caused loading of object code if :use-module was
	applied to the module itself.

1998-12-11  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>

	* Makefile.am: Removed setf.scm.

	* setf.scm: Removed.  1. It was buggy.	2. It was unschemey.
	(These shortcomings were my fault.)

1998-12-10  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>

	* boot-9.scm (environment-module): New procedure.

1998-12-07  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>

	* Makefile.am: Added setf.scm.

1998-12-05  Christian Lynbech  <chl@tbit.dk>

	* setf.scm: New file.  Adds the new forms `setf!' and `setter'
	which implements generalized references a la Common LISP.

1998-12-02  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>

	* boot-9.scm (process-define-module): Added new specifier
	:autoload MODULENAME BINDINGS to the define-module form.
	The autoload specifier tells the module system to load the module
	MODULENAME at the first occasion that any variable with its name
	among BINDINGS is referenced.
	(make-autoload-interface): New procedure:  Constructs a stand-in
	for the public interface for the module to be autoloaded.

1998-12-01  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>

	* boot-9.scm (*suppress-old-style-hook-warning*): Set this to #t
	if you don't want the old style hook warnings.

1998-12-01  Christian Lynbech  <chl@tbit.dk>

	* boot-9.scm (try-using-libtool-name): Fix check on dlname to make
	sure that it isn't empty, as it is when we are only buidling
	static libraries.

1998-11-27  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>

	* session.scm (arity): New procedure.

1998-11-26  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>

	* boot-9.scm: Use run-hook instead of run-hooks everywhere.

1998-11-26  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>

	* boot-9.scm (run-hooks, add-hook!, remove-hook!): Added temporary
	code for backward compatibility until people have had time to
	adapt to the new hooks.

1998-11-23  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>

	* boot-9.scm (beautify-user-module!): Beautify also if public
	interface is set to the module itself.	In this way we can use
	beautify-user-module! to beautify a module prepared for object
	code.
	(process-define-module): Special case: Try to load object code as
	well if a module does :use-module on itself.

	* boot-9.scm: Bugfix: Since boot-9.scm is now loaded from
	invoke_main_func, we can no longer be sure that all modules have
	been registered when boot-9.scm is loaded.
	(register-modules): New function: Register and tag modules
	registered by scm_register_module_xxx since last call to this
	function.  Modules are tagged with the dynamic object passed as
	argument.  (Already linked modules should be tagged with #f.)
	(init-dynamic-module, link-dynamic-module): Call register-modules
	first to register linked modules.

	* boot-9.scm (init-dynamic-module): Remove module from
	registered-modules as soon as possible in case we are recursively
	invoked; Set public interface before doing the dynamic-call.
	
	* boot-9.scm (map-in-order): Removed (replaced by scm_serial_map).
	(abort-hook, before-error-hook, after-error-hook,
	before-backtrace-hook, after-backtrace-hook, before-read-hook,
	after-read-hook, exit-hook): Make hooks with `make-hook'.

	* boot-9.scm: Make hooks first class citizens and make them easier
	to use from C:
	(make-hook, add-hook!, remove-hook!, run-hooks): Moved to
	libguile/feature.c.

	* boot-9.scm: Added warnings about bindings used in
	libguile/modules.c: the-module, set-current-module,
	make-modules-in, beautify-user-module!, module-eval-closure.

1998-11-21  Mikael Djurfeldt  <mdj@kenneth>

	* boot-9.scm (the-environment): New special form: Returns an
	object representing the current local evaluation environment.
	This object can be used in `local-eval' and `defined?'.

1998-11-13  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>

	* boot-9.scm (collect): New syntax.  Similar to begin but returns
	a list of the results of all forms in the sequence instead of the
	result of the last form.

1998-11-10  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>

	* boot-9.scm (values, call-with-values): Moved here from
	syncase.scm.

	* syncase.scm (values, call-with-values): Moved to boot-9.scm.

	* boot-9.scm (readline-options, readline-enable, readline.disable,
	readline-set!: New options interface.

	* readline.scm (readline-port): Use readline-options-interface.

1998-11-05  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>

	* boot-9.scm: Set the repl start module in `top-repl' instead of
	at the end of boot-9.scm.

1998-11-01  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>

	* emacs.scm (format): Bugfix: Handle multiple arguments
	correctly.  (Thanks to Thien-Thi Nguyen.)

1998-11-01  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>

	* boot-9.scm (exit-hook): New hook: Is run at the very end of an
	interactive session.
	(top-repl): Run exit-hook on exit.

	* readline.scm (readline-port): Maybe read history; Maybe write
	history at exit (add to exit-hook).

Fri Oct 30 15:15:37 1998  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>

	* readline.scm (make-readline-port): Bugfixed last change...

1998-10-28  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>

	* readline.scm (make-readline-port): Don't set prompt to "... " if
	read line was empty.

1998-10-19  Jim Blandy	<jimb@zwingli.cygnus.com>

	* boot-9.scm, debug.scm, expect.scm, hcons.scm, lineio.scm,
	r4rs.scm, slib.scm, threads.scm: Update copyright years.

	* getopt-gnu-style.scm, slib.scm: Add copyright notice.

	Talked to Stallman.  Actually, the syntax-case copyright is no
	problem.  Duh.
	* Makefile.am (ice9_sources): Revert last change.
	* syncase.scm, psyntax.pp, psyntax.ss: Added again.
	* Makefile.in: Regeneretade.

	* boot-9.scm: Don't assume that this file is loaded just before
	entering a read-eval-print loop.  Turn code to load (ice-9 emacs)
	into...
	(load-emacs-interface): New function.
	(top-repl): Call it, if use-emacs-interface is defined and true.
	At this point, we *do* know we're about to enter a REPL.

	We can't include Kent Dybvig's syntax-case macro expander in the
	core Guile distribution, because we don't have copyright
	assignments for this code.  We can certainly distribute them as a
	separate package, but Guile should be FSF code.
	* syncase.scm, psyntax.pp, psyntax.ss: Removed.
	* Makefile.am (ice9_sources): Removed syncase.scm, psyntax.pp, and
	psyntax.ss.
	* Makefile.in: Regenerated.

	* Makefile.am (ice9_sources): Add getopt-gnu-style.scm.
	* Makefile.in: Regenerated.

1998-10-18  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>

	* boot-9.scm: Added extended read syntax for byte vectors #y(...)
	and short vectors #h(...).

1998-10-14  Jim Blandy	<jimb@zwingli.cygnus.com>

	* calling.scm (excursion-function-syntax): Use a sequence of
	set!'s, not a single multi-variable set!; we removed support for
	that syntax a long time ago.  (Thanks to Shuji Narazaki.)

1998-10-12  Jim Blandy	<jimb@zwingli.cygnus.com>

	* r4rs.scm (OPEN_READ, OPEN_WRITE, OPEN_BOTH): Don't bother
	testing software-type here.  That's the least of our Windows
	porting issues, and it's done wrong anyway.

1998-10-09  Jim Blandy	<jimb@zwingli.cygnus.com>

	* boot-9.scm (read-path-list-notation-warning): New function:
	print a warning the first time we see `#/' notation.

	* q.scm (sync-q!, q?, q-remove!, q-push!, enq!): Lots of bugs, and
	(eq?  #f '()) assumptions.  Make functions that aren't documented
	to return anything else return the queue itself.  (Bug report from
	Michael Livshin --- thanks!)

1998-08-21  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>

	* debug.scm (trace-entry, trace-exit): Removed re-enabling of
	trace flag.

	* boot-9.scm (make-options): Bugfix: Changed pair? --> list? in
	order to allow the empty list as arg.
	(error-catching-loop): Use `with-traps' to create a dynamic
	context with traps enabled.

1998-08-19  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>

	* boot-9.scm: Removed (ice-9 regex) from use-list of (guile)
	module.
	(try-using-libtool-name): Removed dependency on (ice-9 regex).

1998-08-15  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>

	* boot-9.scm: Make the root module use (ice-9 regex) if
	available.  The dynamic linking facilities in boot-9.scm are
	currently dependent upon regular expressions.  My change of
	1998-07-14 removed (ice-9 regex) from the use-list of the root
	module and thereby destroyed dynamic linking.

1998-07-29  Jim Blandy	<jimb@zwingli.cygnus.com>

	* Makefile.in: Regenerated using the last public version of
	automake, not the hacked Cygnus version.

1998-07-28  Jim Blandy	<jimb@zwingli.cygnus.com>

	* Makefile.in: Regenerated, after removing Totoro kludge.

1998-07-28  Jim Blandy	<jimb@totoro.red-bean.com>

	* getopt-gnu-style.scm: New file.  (Thanks to Russ McManus.)

1998-07-26  Jim Blandy	<jimb@zwingli.cygnus.com>

	* Makefile.in Rebuilt, for config changes in parent dir.

1998-07-21  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>

	* readline.scm (make-readline-port): Set prompt string to "... "
	after first read line.	(Thanks to Richard Polton.)

1998-07-19  Jim Blandy	<jimb@zwingli.cygnus.com>

	* lineio.scm (make-line-buffering-input-port): Don't use
	ungetc-char-ready?, since we don't provide that function any
	more.  The unread-string function doesn't interact properly with
	any of the standard I/O functions anyway.  (Thanks to Andrew
	Archibald.)

	* hcons.scm (hashq-cons-assoc): Don't assume the empty list is
	false.	Return false when we cannot find a matching entry in the
	list.  (Thanks to Andrew Archibald.)

1998-07-16  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>

	* boot-9.scm (export, export-syntax): New special forms: Export
	bindings from a module.	 `(export name1 name2 ...)' can be used at
	the top of a module (after `define-module') to specify which names
	should be exported.  It can be used as an alternative to
	`define-public'.  `export-syntax' works equivalently to `export'
	but is intended for export of syntactic keywords.
	(Thanks to Thien-Thi Nguyen.)

1998-07-15  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>

	* boot-9.scm: Renamed module `(guile-repl)' --> `(guile-user)'.

1998-07-14  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>

	* boot-9.scm: Let the user start in module `(guile-repl)' instead
	of module `(guile)'.  Also make sure that `(guile-repl)' uses
	suitable modules.  This change improves Guile stability
	substantially since bindings will only be copied from the root
	module: If the user redefines builtins in `(guile-repl)' it won't
	affect the internal operation of Guile itself.

1998-06-19  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>

	* boot-9.scm (load-module): When loading files from within files
	themselves being loaded: Use the directory path of the file being
	loaded as root for relative filenames.	(After suggestion by
	Steven G. Johnson.)

1998-06-15  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>

	* emacs.scm (emacs-load): New feature: Eval in specified module.

1998-06-14  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>

	* readline.scm: Typo in regex module name.

1998-06-13  Mikael Djurfeldt  <mdj@barbara.nada.kth.se>

	* readline.scm (apropos-completion-function): regexp-quote text to
	be completed.

1998-06-11  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>

	* debug.scm, emacs.scm: Bugfix: Treat `the-last-stack' as a fluid.

1998-06-09  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>

	* boot-9.scm: Check that (current-input-port) is a tty before
	enabling readline.  (Thanks to Michael N. Livshin.)

1998-06-07  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>

	* boot-9.scm (use-syntax): Turned into a macro inorder to be
	similar in use to `use-modules'.
	Example: (use-syntax (ice-9 syncase)) will 1. load the module
	(ice-9 syncase), and, 2. install the procedure `syncase' as eval
	transformer.
	(internal-use-syntax): New procedure.
	(process-define-module): Use `internal-use-syntax'.

1998-05-19  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>

	* Makefile.am (ice9_sources): Add emacs.scm.

1998-05-13  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>

	* readline.scm: Use the new readline facilities: Add the
	possibility to control input and output ports; Add apropos
	completion.

	* boot-9.scm: Antirevert Jim's readline code which he reverted
	19971027 and adapt it to the current readline interface.
	
	* boot-9.scm (top-repl): Only enable readline if not using the
	Emacs interface; Only use repl prompt when using the readline port
	from repl-read.	 (We don't want to see it when calling `read'.)

	* boot-9.scm (remove-hook!): Parenthesis bug.

1998-05-11  Mikael Djurfeldt  <mdj@kenneth>

	* boot-9.scm: Load readline module if readline is present.

	* readline.scm (apropos-completion-function): New procedure:
	Symbolic completion.  (Thanks to Andrew Archibald!)

1998-04-22  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>

	* boot-9.scm (process-define-module): Added keyword use-syntax.

1998-04-19  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>

	* nonblocking.scm: Removed.  libguile is now inherently
	nonblocking through the use of scm_internal_select.
	
	* emacs.scm: Removed use of nonblocking.scm.

	* gwish.scm, gtcl.scm: Removed.	 tcltk.scm has made these
	obsolete.
	
1998-04-15  Mikael Djurfeldt  <mdj@nada.kth.se>

	* runq.scm (runq-control): Corrected spelling of enqueue!.
	(Thanks to Karl M. Hegbloom.)

1998-03-30  Mikael Djurfeldt  <mdj@nada.kth.se>

	* boot-9.scm: Added new run-time option interface eval-options.

1998-03-28  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>

	* boot-9.scm (remove-hook!): New macro.	 (Thanks to Maciej
	Stachowiak.)

1998-01-30  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>

	* threads.scm: Added simple error and signal handler.
	(make-thread, begin-handler): Use this handler.	 The most
	important effect of this is that signals get unmasked.
	Previously, when a signal was thrown signals remained masked
	(signals get masked when a signal is taken) which influenced other
	threads.

1998-01-01  Tim Pierce	<twp@skepsis.com>

	A better fix to the SLIB identity problem -- thanks to Marius Vollmer.
	* slib.scm (identity): Unmake public.
	(slib:eval): Evaluate inside `slib-module'.

1997-12-24  Tim Pierce	<twp@skepsis.com>

	* boot-9.scm: Doc fix.

	* slib.scm (identity): Made public.
	(home-vicinity): New function (from SLIB/Template.scm).

1997-12-13  Tim Pierce	<twp@skepsis.com>

	* boot-9.scm (read-line): Rewritten to call %read-line for
	improved speed.	 Minor user-visible changes: the new functions are
	hardwired to treat the LFD character as signifying end-of-line, so
	changing `scm-line-incrementors' will no longer affect the
	behavior of read-line.	On platforms which do not represent
	end-of-line with a LFD character, read-line should behave more
	like native line-processing facilities, but there is still a ways
	to go here.

Sat Nov 29 01:24:46 1997  Mikael Djurfeldt  <mdj@kenneth>

	* boot-9.scm (error-catching-loop, save-stack): `the-last-stack'
	is now a fluid.

1997-11-28  Tim Pierce	<twp@skepsis.com>

	* boot-9.scm (find-and-link-dynamic-module): If a module directory
	contains a .la file (a libtool support file), attempt to extract
	the shared library name from that file.	 If the .la file does not
	exist, try to link against a .so file.	Libtool-generated compiled
	modules should load more cleanly in Guile now.
	(try-using-libtool-name, try-using-sharlib-name): New functions.

Sun Nov	 9 06:10:59 1997  Gary Houston	<ghouston@actrix.gen.nz>

	* boot-9.scm (set-batch-mode?!, batch-mode?): initialize more
	usefully so they will work from a script.

1997-10-31  Marius Vollmer  <mvo@zagadka.ping.de>

	* boot-9.scm (inherit-print-state): Moved definition to the
	neighborhood of the record code.

Mon Oct 27 02:05:49 1997  Jim Blandy  <jimb@totoro.red-bean.com>

	* boot-9.scm: Revert changes to this file from Oct 23.	It turns
	out to interact badly with the Emacs support and the Tcl/Tk
	support.  It's not a high enough priority at the moment to be
	worth fixing.  I'm leaving the other readline support in, though.

Sat Oct 25 14:23:22 1997  Jim Blandy  <jimb@totoro.red-bean.com>

	* Makefile.am: Include readline.scm in the list of files to be
	installed, so Guile can find it for interactive use.
	* Makefile.in: Regenerated.

Thu Oct 23 01:00:33 1997  Jim Blandy  <jimb@totoro.red-bean.com>

	Add support for readline function.
	* readline.scm: New module.
	* boot-9.scm (repl-reader): New function.
	(scm-style-repl): Call repl-reader, instead of doing the reading
	ourselves.  Remove repl-report-reset; it was never used for
	anything.
	(top-repl): If we've got the readline primitives, then redefine
	repl-reader to use them.
	If we've got the readline primitives, import the readline module.

	* ls.scm (ls, lls): Don't assume (eq? #f '()).

Wed Oct 22 18:26:57 1997  Jim Blandy  <jimb@totoro.red-bean.com>

Wed Oct	 8 03:16:01 1997  Gary Houston	<ghouston@actrix.gen.nz>

	* (error-catching-loop): new local variable "interactive".  if
	#f, abort terminates the process.
	(set-batch-mode?!, batch-mode?): new closures, defined in 
	error-catching-loop.  the names are from scsh.

	(record-type-vtable): User fields "prpr" (printer is no longer a
	user field).
	(record-type-name, record-type-fields): Decreased slot index by

Thu Oct	 2 12:00:00  Marius Vollmer  <mvo@zagadka.ping.de>

	* boot-9.scm (inherit-print-state): New experimental function.

Tue Sep 30 13:12:48 1997  Jim Blandy  <jimb@totoro.red-bean.com>

	* slib.scm (slib:load): slib:load first tries to load the file
	named NAME, then NAME.scm.  On error, report the error occuring at
	the first attempt (NAME) rather than the second (NAME.scm).

	the make-options macro so that we needn't refer to a global
	symbol.

Sun Sep 28 21:40:24 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>

	* debug.scm: Moved options interface procedures to boot-9.scm.

	* slib.scm: Added hack which transfers syntactic information from
	the builtin variable `define' to the slib version if module (ice-9

	syncase) and with the current directory containing the psyntax.ss
	source.
	Added hack to transfer syntactic information from the builtin
	variable `define' to the slib version if module (ice-9 slib) has
	been loaded.

	* emacs.scm (emacs-load): Added new parameter `module'.

	* syncase.scm (putprop, getprop): Modified to use the object

	Changed `builtin-variable' calls to `define-public' calls.
	Setup the hooks sc-expand and sc-interface.

	* boot-9.scm (sc-interface, sc-expand): New builtin variables.

	the syncase interface.

Thu Sep	 4 14:57:04 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>

	* syncase.scm (putprop): Temporary fix which publishes new syntax
	globally (the old behaviour was complex and connected to the inner
	workings of the current module system).

Wed Sep	 3 21:29:13 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>

	* psyntax.ss: Updated.
	psyntax.pp: Bugfix: Previous version had some leading "t":s cut
	off!

Tue Sep	 2 00:26:42 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>

	* boot-9.scm (gensym): Removed (replaced by primitive).
	(obarray-gensym): Rewritten to use `gensym'.
	(gentemp): Rewritten to use `gensym'.

Mon Sep	 1 20:08:32 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>

	* gtcl.scm (make-tcl-binder): Rewritten to choose bindings
	according to the following priorities:
	1. tcl bindings which are present in override-scheme-list
	2. bindings from the-scm-module
	3. tcl bindings
	This way the gtcl module can occur first in the use-list without
	disabling the scheme interpreter.
	(new-interpreter): New function.

	* gwish.scm: Moved initialization code for the-interpreter to
	gtcl.scm; Moved name space cleaning code to gtcl.scm and rewrote
	it; Call `new-interpreter'; Don't :use-module (guile).

	* session.scm (apropos-internal): Musn't initialize symbol
	accumulator with a constant pair.  That led to mutation of the
	source!

	* session.scm (vector-for-each): Removed.
	(apropos): vector-for-each --> array-for-each.
	(apropos-internal): New function.  Return list of accessible
	symbols matching regexp.

	* debug.scm (frame-number->index): New function.  Convert frame
	number (as displayed in the backtrace) to frame index (to be used
	in stack-ref).

	* emacs.scm (emacs-load): New arguments: interactivep: when
	non-false, send back results to Emacs; colnum: Column number;
	Use modules (ice-9 debug) and (ice-9 session);
	(no-stack, no-source): New simple-actions;
	(result-to-emacs): New procedure. Sends data to Emacs via the

	that we now should set the port line count to the specified value
	(linum) instead of (- linum 1).

	* slib.scm (slib:load): Use load-from-path instead of
	primitive-load-path so that backtraces get narrowed properly at
	the top.

	* boot-9.scm (top-repl): Save stack already in signal handler in
	order to narrow it correctly.
	(save-stack): Adjust narrowing tag for the top of load-stacks.

Sat Jul 26 21:30:10 1997  Marius Vollmer  <mvo@zagadka.ping.de>

	* boot-9.scm (with-fluids): New macro to go with the
	builtin `with-fluids*'.

Thu Jul 24 04:28:11 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>

	* slib.scm (install-require-module): In newer versions of slib
	*catalog* is #f until the first access.	 Therefore we call
	require:provided? for a random feature if *catalog* is #f.

Wed Jul 23 20:13:04 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>

	* boot-9.scm (make-list): Remove the definition of this function
	from the (ice-9 common-list) module; make the `init' argument
	optional in the	scm module's definition, to match the deleted
	definition.  Harmony reigneth?	(Thanks to Bernard URBAN.)

Sun Jun 22 18:33:17 1997  Jim Blandy  <jimb@floss.red-bean.com>

	Try to detect when people are using one version of libguile and a
	different version of ice-9.  People have been skewing things and
	sending in bug reports.
	* version.scm.in: New file, which the configure script munges to
	produce version.scm, which contains the ice-9 config stamp.
	* boot-9.scm: Compare the libguile and ice-9 config stamps;
	display a warning if the two are different.
	* Makefile.am: Install version.scm, but don't distribute it.

	(expect-strings): Use make-regexp and regexp-exec, instead of
	regcomp and regexec.  We've omitted the REG_NEWLINE flag; hope
	that's okay.

	* boot-9.scm (with-regexp-parts): Comment this out.  It has no
	users in the core, and relies on mildly hairy details of the old
	regexp interface.

	* test.scm: Re-enable tests asserting that '() is true, and not a
	boolean.  This stuff has been true for a while.

	* boot-9.scm (ipow-by-squaring, butlast): Fix uses of outdated

	* slib.scm (slib:load): Use primitive-load-path instead of
	basic-load.  This is probably wrong, but hopefully the entire
	source access system will be revised soon anyway, and this will
	make require behave more like Emacs Lisp's require.  If this
	breaks something, please let me know.  Maybe this is real dumb.

Thu May 29 02:36:48 1997  Jim Blandy  <jimb@floss.cyclic.com>

	* regex.scm: Add a module declaration.	Use DEFINE-PUBLIC everywhere.
	* boot-9.scm: If the `regex' feature is present, use the module
	(ice-9 regex).

	* regex.scm: New file.
	* Makefile.am (subpkgdata_DATA): Add regex.scm.

	threads.scm: New address for FSF.

Fri May 16 04:09:45 1997  Jim Blandy  <jimb@floss.cyclic.com>

Thu May 15 07:56:08 1997  Gary Houston	<ghouston@actrix.gen.nz>

	* expect.scm: use gettimeofday instead of get-internal-real-time
	and use a floating point timeout when calling select.  Untested,
	since the regex library is currently AWOL.

Wed May 14 21:00:30 1997  Jim Blandy  <jimb@floss.cyclic.com>

	* boot-9.scm (eval-string): Function deleted; it was already
	implemented in C, so there's no point in making a divergable copy
	here.

Tue May 13 16:40:06 1997  Jim Blandy  <jimb@floss.cyclic.com>

	* Makefile.in: Regenerated, using automake-1.1p.

Tue May 13 16:40:06 1997  Jim Blandy  <jimb@floss.cyclic.com>

	* Makefile.in: Regenerated, using automake-1.1p.

Tue May 13 02:48:49 1997  Gary Houston	<ghouston@actrix.gen.nz>

	* boot-9.scm (error-catching-loop): don't read a line from
	current input when quit is encountered, the previous change
	fixes this too.

Mon May 12 19:00:21 1997  Jim Blandy  <jimb@floss.cyclic.com>

	* boot-9.scm (scm-style-repl): After reading an expression,
	consume any trailing newline (perhaps preceded by whitespace), to
	avoid screwing up GDB.	More detail in comments.

Mon May	 5 13:18:38 1997  Jim Blandy  <jimb@floss.cyclic.com>

	* Makefile.am (ETAGS_ARGS): New variable, since we're not treating
	the Scheme code like code yet.

Sun Apr 27 17:56:09 1997  Jim Blandy  <jimb@floss.cyclic.com>

	* aclocal.m4: Removed; unnecessary, given changes of Apr 24.

	* Makefile.am (subpkgdatadir): Use "ice-9" instead of "@module@";
	we're not using AM_INIT_GUILE_MODULE any more.
	* Makefile.in: Regeneratitetedrerd.

Thu Apr 24 01:33:33 1997  Jim Blandy  <jimb@floss.cyclic.com>

	Get 'make dist' to work again.
	* Makefile.am (EXTRA_DIST): Remove PLUGIN files.
	* Makefile.in: Regenerated, like two tons of fleas.

	Changes for reduced Guile distribution: one configure script,
	no plugins.
	* configure.in, configure: Removed.
	* Makefile.in: Regenerated.

Sat Apr 19 08:03:50 1997  Jim Blandy  <jimb@floss.cyclic.com>

	* boot-9.scm (eval-string, command-line, load-user-init): New
	functions.

Sat Apr 12 08:27:05 1997  Gary Houston	<ghouston@actrix.gen.nz>

	* boot-9.scm (log10): defined.

Tue Apr	 1 17:46:49 1997  Gary Houston	<ghouston@actrix.gen.nz>

	* expect.scm (expect-select): correct the millisecond timeout
	arithmetic (from Marko.Kohtala@ntc.nokia.com).
	
Mon Mar 31 03:23:19 1997  Gary Houston	<ghouston@actrix.gen.nz>

	* boot-9.scm (open-input-pipe, open-output-pipe): defined here
	instead of in libguile.
	(tm:sec etc.) new accessors for broken-down time.

	sockaddr:port): new functions.

Wed Mar 19 04:50:34 1997  Gary Houston	<ghouston@actrix.gen.nz>

	* boot-9.scm: define accessor procedures for the objects returned
	by getpw, getgr, gethost, getnet, getproto, getserv (e.g.,
	passwd:name, where the first component is the name of the C structure
	and the second is the unprefixed C member name.)

Tue Mar 18 18:39:31 1997  Gary Houston	<ghouston@actrix.gen.nz>

	* boot-9.scm (setpwent, setgrent, sethostent, setnetent, setprotoent,
	setservent): no longer take an argument, it was bogus.

Thu Mar 13 00:13:41 1997  Gary Houston	<ghouston@actrix.gen.nz>

	* boot-9.scm (scm-error): deleted, reimplemented in C.

Mon Mar 10 15:48:31 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>

	* boot-9.scm (process-define-module): Modified to handle both
	keywords and symbols.

Sat Mar	 8 04:32:44 1997  Gary Houston	<ghouston@actrix.gen.nz>

	* slib.scm: update read usage.

	* r4rs.scm: update primitive-load usage.
	Don't define read-sharp.

	* boot-9.scm: use read-hash-extend to install extra read syntax.
	(read-sharp): removed.
	Adjust usage of primitive-load-path, read, which no longer take
	case_i or read-sharp arguments.

Sat Mar	 8 00:07:54 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>

	* boot-9.scm: Added loading of session support module.

	* debug.scm: Removed `display-application'.  (Replaced by
	primitive procedure.)

	* boot-9.scm (beautify-user-module!): Don't add the root module
	interface to the end of the use-list of the root module.

	* boot-9.scm: repl-quit, repl-abort: obsolete variables deleted.

Wed Mar	 5 20:30:24 1997  Gary Houston	<ghouston@actrix.gen.nz>

	* boot-9.scm: check use-emacs-interface for emacs support.

Sun Mar	 2 19:47:14 1997  Gary Houston	<ghouston@actrix.gen.nz>

	* boot-9.scm (scm-style-repl): call repl-report-start-timing if
	read gets EOF.
	* (exit): alias for quit.

Sun Mar	 2 05:25:11 1997  Gary Houston	<ghouston@actrix.gen.nz>

	* boot-9.scm (error-catching-loop thunk): use a status variable to
	return the quit args.
	(scm-style-repl): call -quit, passing return value from
	error-catching-repl.  Make -quit return its args.
	stand-alone-repl: comment out, since it seems unused.

	(error-catching-loop thunk): discard trailing junk after a (quit).

Sat Mar	 1 15:24:39 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>

	* boot-9.scm: Removed the old printer code.

	* r4rs.scm (apply, call-with-current-continuation): Added comment
	explaining why apply and call/cc need to be closures.

	* boot-9.scm (apply, call-with-current-continuation): Bugfix:
	Removed. These definitions are already present in r4rs.scm.

	* debug.scm (trace-entry, trace-exit): Check that we're on a repl
	stack before printing traced frames; Re-enable trace flag at end
	of handlers.

Sat Mar	 1 00:10:38 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>

	* debug.scm: Add hook for reset of trace level at abort.

	* boot-9.scm (run-hooks): New procedure.
	(add-hooks!): New macro.
	Change hooks to use these functions.

	* debug.scm: *Warning* This feature is a bit premature.	 I add
	it anyway because 1. it is very useful, and, 2. you can start
	making it less premature by complaining to me and by modifying
	the source! :-)
	(trace): Given one or more procedure objects, trace each one.
	Given no arguments, show all traced procedures.
	(untrace): Given one or more procedure objects, untrace each one.
	Given no arguments, untrace all traced procedures.  The tracing in
	Guile have an advantage to most other systems: We don't create new
	procedure objects, but mark the procedure objects themselves.
	This means that also anonymous and internal procedures can be
	traced.

	* boot-9.scm (error-catching-loop): Added handling of apply-frame
	and exit-frame exceptions.
	
	* boot-9.scm (assert-repl-prompt, the-prompt-string): Removed.
	(set-repl-prompt!): Setter for repl prompt.
	(scm-style-repl): If prompt is #f, don't prompt; if prompt is a
	string, display it; if prompt is a thunk, call it and display its
	result; otherwise display "> ".
	(Change suggested by Roland Orre <orre@nada.kth.se>.)

	* r4rs.scm (%load-verbosely): Reverted change to
	`module-defined?', since the module system isn't bootstrapped when
	we load r4rs.scm.  This is just a temporary fix to make the
	repository version runnable.

Thu Feb 27 23:25:47 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>

	* boot-9.scm: Removed the enabling of debug evaluator and
	recording of source code positions.  This was placed there for our
	convenience, but it has already sneaked into the distribution
	once... so we'd better add this in our local copies instead when
	we need it.  (These options are normally enabled at the end of
	boot-9.scm when loading the debug module.)

Thu Feb 27 16:04:45 1997  Marius Vollmer  <mvo@zagadka.ping.de>

	* boot-9.scm (module-defined?): New function.
	(macroexpand-1, macroexpand): Use local-ref instead of defined?
	and eval.
	* r4rs.scm (%load-verbosely): Use "module-defined?" instead of
	"defined?".
	* slib.scm (defined?): New function to take the place of the
	builtin "defined?".  It allways examines the slib module.

Mon Feb 24 21:46:15 1997  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>

	* configure.in: Added AM_MAINTAINER_MODE

Sat Feb 15 04:51:20 1997  Gary Houston	<ghouston@actrix.gen.nz>

	* boot-9.scm (read-sharp): define directly, don't go through a
	%read-sharp layer.

Tue Feb 11 08:45:48 1997  Gary Houston	<ghouston@actrix.gen.nz>

	* boot-9.scm (uniform-vector-set!): use uniform-array-set1!, not
	uniform-vector-set1! which doesn't exist.

Mon Feb 10 03:01:48 1997  Mikael Djurfeldt  <mdj@kenneth>

	* boot-9.scm (backtrace): Removed.  (A C version now exists in
	backtrace.c.)

Fri Jan 24 06:05:36 1997  Gary Houston	<ghouston@actrix.gen.nz>

	* boot-9.scm (read-line!, read-delimited!, read-delimited,
	read-line): new	procedures, see libguile/ChangeLog.

Thu Jan 16 17:07:03 1997  Marius Vollmer  <mvo@zagadka.ping.de>

	Added dynamic linking of modules. See libguile/DYNAMIC-LINKING.

	* boot-9.scm (split-c-module-name, convert-c-registered-modules,
	init-dynamic-module, dynamic-maybe-call,
	find-and-link-dynamic-module, link-dynamic-module,
	try-module-dynamic-link, registered-modules): New definitions for
	dynamic linking of modules.
	(resolve-module): Try to dynamically link the requested module
	after failing to load it as Scheme code.

Wed Jan	 8 05:50:14 1997  Gary Houston	<ghouston@actrix.gen.nz>

	* boot-9.scm (getservbyport, getservbyname): remove stray %.

Tue Jan	 7 20:02:24 1997  Jim Blandy  <jimb@floss.cyclic.com>

	* boot-9.scm (and=>): Rename THUNK argument to PROCEDURE, 'cos
	that's what it is.

	* lineio.scm (make-line-buffering-input-port): Properly test for
	the case of an empty buffer list.  The old code assumed that '()
	was false.

Mon Jan	 6 01:13:53 1997  Mikael Djurfeldt  <mdj@kenneth>

	* boot-9.scm (use-modules): New macro (from Marius Vollmer).
	(use-modules <module name> ...) Put the the modules named by
	<module name> ... on the use list of the current module.

Sun Jan	 5 15:52:59 1997  Jim Blandy  <jimb@floss.cyclic.com>

	* boot-9.scm (error-catching-loop): Remove message saying that
	typing "$" will put you in the debugger.  This isn't implemented
	yet.

Sun Dec 22 23:27:25 1996  Jim Blandy  <jimb@floss.cyclic.com>

	* boot-9.scm (delq-all!): Function deleted; delq!'s semantics have
	been fixed, so this function is superfluous.
	(transform-usage-lambda): Use delq!, not delq-all!.

Tue Dec 17 20:36:45 1996  Marius Vollmer  <mvo@zagadka.ping.de>

	* boot-9.scm (resolve-module): New optional parameter that
	controls whether autoloading is attempted or not. Default is #t.
	(process-define-module): Don't autoload the defined module.
	(try-module-autoload): Don't autoload the directory modules.

	* boot-9.scm (process-define-module): Ensure that the-scm-module
	is last in the `uses' list to allow shadowing builtin
	bindings. All :use-module options are added in the order they
	appear in the arguments but before anything already on the list
	(such as the-scm-module).

Wed Dec 11 21:06:05 1996  Gary Houston	<ghouston@actrix.gen.nz>

	* slib.scm (slib-parent-dir): throw error if #f returned from
	%search-load-path.

Sat Nov 30 23:57:28 1996  Tom Tromey  <tromey@cygnus.com>

	* PLUGIN/greet, PLUGIN/split.sed, PLUGIN/this.configure: Removed.
	* Makefile.am, aclocal.m4: New files.
	* configure.in: Updated for Automake.

Wed Nov 27 14:16:14 1996  Marius Vollmer  <mvo@zagadka.ping.de>

	* boot-9.scm (macroexpand-1, macroexpand), slib.scm
	(slib:features), r4rs.scm (%load-verbosely): "defined?" is now a
	function, use it accordingly.
	
Thu Nov 21 11:12:10 1996  Jim Blandy  <jimb@floss.cyclic.com>

	It's an "eval closure", not an "eval thunk."  A thunk is a
	function of no arguments.
	* boot-9.scm (module-type): Rename module field.
	(make-module, eval-in-module, make-root-module,
	set-current-module): Uses changed. 
	(module-eval-closure, set-module-eval-closure!,
	root-module-closure): Renamed from module-eval-thunk,
	set-module-eval-thunk!, root-module-thunk.
	(set-current-module): Change uses of *top-level-lookup-thunk* to
	*top-level-eval-closure*.

Wed Nov 20 14:45:27 1996  Jim Blandy  <jimb@totoro.cyclic.com>

	* slib.scm (slib-parent-dir): Use string-length, not length.
	(Thanks to Bernard Urban.)

Sat Nov	 2 20:00:42 1996  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>

	* boot-9.scm: The debugging evaluator and recording of positions
	aren't enabled by default any longer (they are switched on in
	debug.scm).  But during development we want to have them also
	*inside* boot-9.scm.  Therefore, two lines are added at the
	beginning of boot-9.scm to enable these.
	
	Call `provide' so that `records' are included among the
	`*features*'.
	
	The scheme for saving the stack has been adjusted: save-stack is
	now commonly available for saving the stack.  Calling `save-stack'
	sets a flag `stack-saved?' which prevents overwriting the stack.
	`stack-saved?' is reset at `abort'.
	
	Spelling correction: seperate --> separate.
	
	Removed `:'s that had creeped into some comments.
	
	The repl now doesn't print #<unspecified> results any longer
	If the user wants to see this, he can do
	(assert-repl-print-unspecified #t) in his startup file.
	
	The user now gets a friendly message instead of a backtrace at
	error.
	
	Added `before-read-hook'.
	
	Load module (ice-9 emacs) if option `-e' was specified.
	
	(provide): New function.
	
	(error): Save stack at entry, so that Guile entrails won't show up
	in backtraces.
	
	(backtrace): New function.
	
	(save-stack): Can now take arbitrary number of stack narrowing
	specifier pairs.  The first specifier in a pair controls inner
	border, the second the outer border.  A number means cut that
	number of frames, a procedure object means cut until that object
	is found in operator position in a frame.

	* debug.scm: Enable debugging evaluator and recording of positions
	by default.

	* slib.scm (slib:load): Adapt to the new behavior of
	primitive-load: It doesn't any longer try both with and without
	".scm" extension.  (We don't want to use %search-load-path here.)
	
	(implementation-vicinity): New function.  slib requires it
	
	(library-vicinity): Updated.
	
	Load "require.scm" in the library-vicinity.
	
	(install-require-vicinity, install-require-module): New functions.
	
Mon Oct 28 17:56:29 1996  Jim Blandy  <jimb@floss.cyclic.com>

	* boot-9.scm (load-from-path): New function.

	* boot-9.scm (try-load, basic-try-load, try-load-module,
	try-load): Deleted.  I don't think they're being used.

	* Makefile.in (scm_files): Add r4rs.scm and test.scm to this list,
	so they'll get distributed.

	Get Guile to be a little less chatty by default.  The new user
	should see as little clutter as possible.
	* r4rs.scm (%load-verbosely): Make this #f by default.
	* boot-9.scm (scm-repl-verbose): Make this #f by default.
	(scm-style-repl): Don't run 'pk' on the value passed to quit.

	* r4rs.scm: New file.
	* boot-9.scm: Load r4rs.scm, first thing.
	(OPEN_READ, OPEN_WRITE, OPEN_BOTH, *null-device*, open-input-file,
	open-output-file, open-io-file, close-input-port,
	close-output-port, close-io-port, call-with-input-file,
	call-with-output-file, with-input-from-port, with-output-to-port,
	with-error-to-port, with-input-from-file, with-output-to-file,
	with-error-to-file, with-input-from-string, with-output-to-string,
	with-error-to-string, the-eof-object): Definitions moved to
	r4rs.scm.  Not all of them are R4RS, but those that are use those
	that are not.
	(load, %load-verbosely, %load-announce): Moved, along with code to
	set %load-hook, to r4rs.scm.

	* test.scm: New file.

	* boot-9.scm (integer?): Definition deleted, in favor of the one
	present in libguile (which used to be called int?).  I have no
	idea why integer? didn't just call int? to begin with.

	* boot-9.scm (<, <=, =, >, >=): Definitions in terms of <?, <=?,
	=?, >?, and >=? deleted; they're defined that way by libguile now.

	* boot-9.scm (load): Simplified; primitive-load does most of this
	work now.
	(%load-announce-win): Removed; no longer used.	Set %load-hook to
	call %load-announce.

Sun Oct 27 07:47:03 1996  Gary Houston	<ghouston@actrix.gen.nz>

	* boot-9.scm (stat:dev, stat:ino, stat:mode, stat:nlink, stat:uid,
	stat:gid, stat:rdev, stat:size, stat:atime, stat:mtime,
	stat:ctime, stat:blksize, stat:blocks) accessor functions for stat
	components.
	(file-is-directory?): use stat:type.

Fri Oct 25 03:34:47 1996  Jim Blandy  <jimb@floss.cyclic.com>

	* boot-9.scm (%read-sharp): Don't recognize the `#!' syntax here;
	that's now taken care of in libguile, and in a way compatible with
	SCSH (which this isn't).

Mon Oct 21 18:52:36 1996  Jim Blandy  <jimb@totoro.cyclic.com>

	* boot-9.scm: Formatting tweaks.

Fri Oct 18 01:03:08 1996  Mikael Djurfeldt  <mdj@mdj.nada.kth.se>

	* boot-9.scm (handle-system-error): Added hooks before-error-hook,
	after-error-hook, before-backtrace-hook and after-backtrace-hook
	to the error handler.  E.g.: fancy emacs support could plug into
	these.
	(save-stack): New function.  The stack is now made differently
	depending on the stack id.  (The motivation is to make a better
	choice regarding what stack frames to present to the user.)
	(error-catching-loop): Stack handling code moved outside into
	save-stack.

Thu Oct 17 20:33:08 1996  Gary Houston	<ghouston@actrix.gen.nz>

	* Makefile.in (scm_files): add expect.scm.

	* expect.scm: new file ported from guile-iii.

	* boot-9.scm: remove handle-system-error, after moving the code into
	error-catching-loop.
	Don't set 'throw-handler-default property on error keys.
	Just interpret (almost) any throw with 4 args as an error throw.
	Delete some try-load stuff that was already commented out.

	Second thoughts, keep handle-system-error but call it from
	error-catching-loop.

Tue Oct 15 17:07:20 1996  Jim Blandy  <jimb@floss.cyclic.com>

	* boot-9.scm: Doc fixes.
	(make-module): Rework for readability.
	(make-root-module, make-scm-module): USES argument to make-module
	should be '(), not #f.

	* boot-9.scm (try-load): %sys-load-path has been renamed to
	primitive-load-path; adjust call here.

Tue Oct 15 14:25:01 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>

	* boot-9.scm (signal-handler): Bugfix: Moved the recording of
	the stack to the correct place: when it is decided to generate an
	error-signal.

Mon Oct 14 22:20:30 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>

	* boot-9.scm (error-catching-loop, signal-handler,
	handle-system-error): Backtracing now works for signals aswell;
	Backtracing mechanism can now identify the stack root created by
	start-stack so that the user isn't exposed to system stack frames.

Mon Oct 14 06:05:42 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>

	* Makefile.in: Added threads.scm.
	
Mon Oct 14 04:21:51 1996  Mikael Djurfeldt  <mdj@woody.nada.kth.se>

	* debug.scm (make-enable, make-disable): Simplified.

	* boot-9.scm: Renamed %%throw-handler-default -->
	throw-handler-default.
	((handle-system-error key . arg-list)): Changed the way errors are
	reported.
	((scm-style-repl)): Wrap up the call to eval in a start-stack
	acro.
	((error-catching-loop thunk)): Introduce a lazy-catch into
	error-catching-loop so that the stack can be captured.

Thu Oct 10 22:27:32 1996  Jim Blandy  <jimb@totoro.cyclic.com>

	* mapping.scm (hash-table-mapping): Explicitly request that
	make-vector fill new vectors with '(); this will make it easier to
	port Guile Scheme code to other Schemes.
	* boot-9.scm (make-print-style, make-print-table): Same.

Sun Oct	 6 03:54:59 1996  Gary Houston	<ghouston@actrix.gen.nz>

	* boot-9.scm (load): rewritten again.
	Append "." to the default %load-path.
	(feature?): new function: checks for a symbol in the features list.
	(module-local-variable): remove apparently useless (caddr (list m v
	...))
	(%load-announce): minor formatting change.
	(file-exists?): use access? if posix is featured.
	(file-is-directory?): use stat if i/o-extensions is featured.
	(try-module-autoload module-name): use file-exists? before 
	file-is-directory?

Sat Oct	 5 18:54:03 1996  Mikael Djurfeldt  <mdj@kenneth>

	* boot-9.scm: Added conditional loading of threads.scm.

	* threads.scm: New file.  Modified from the Cygnus-r0.3
	distribution.

	* boot-9.scm (error-catching-loop): Added handling of key
	`switch-repl'.

	* boot-9.scm: Name change %%bad-throw --> bad-throw.

Wed Oct	 2 23:38:44 1996  Jim Blandy  <jimb@totoro.cyclic.com>

	* boot-9.scm (make-record-type, record-constructor): Don't assume
	the empty list is false when parsing the argument list.

Mon Sep 30 22:15:50 1996  Jim Blandy  <jimb@totoro.cyclic.com>

	* boot-9.scm (signal-handler): Clean up logic.

	* boot-9.scm (load): Assume %load-path is always bound.

Sat Sep 28 00:15:37 1996  Gary Houston	<ghouston@actrix.gen.nz>

	* boot-9.scm (error): replace another throw with scm-error.  Throw
	to 'misc-error instead of 'error (no need to distinguish these.)
	Don't set up 'error as a key.
	Set up regex-error as a key, if regex is available.
	(signal-handler): use scm-error, not throw.

	(%try-load, try-load-with-path, %load, load-with-path,
	basic-try-load-with-path, basic-load-with-path,
	try-load-module-with-path,load-module-with-path): deleted, since
	they seem redundant.
	(try-load): define using %try-load, not try-load-with-path.
	(load): rewritten.  load tries to open the file directly and
	with a .scm extension before searching the library directories
	(should "." be added to %load-path?  then load could still open
	directly files starting with "/").
	(try-module-autoload): use load, not load-with-path.
	(%load-indent): deleted, -2 was causing errors.

	(%read-sharp): use port-line, not line-number.

Fri Sep 27 16:23:51 1996  Jim Blandy  <jimb@totoro.cyclic.com>

	* boot-9.scm (%%bad-throw): Delete definition. 1) It's very
	straightforward to provide the equivalent functionality using
	(catch #t ...), so there's no need for the extra complexity.  2)
	Outside the context of a read-eval-print loop (which Guile should
	not require) it's not clear we should do anything more complicated
	than print an error and exit; the user or REPL can establish
	something better if it wants.  3) In that case, it's much more
	robust to just do it in the C code.

Tue Sep 24 06:53:04 1996  Gary Houston	<ghouston@actrix.gen.nz>

	* boot-9.scm (%try-load): define using primitive-load.	Previously

	* boot-9.scm: Name change: value-ref --> local-ref
	resolved-ref --> nested-ref  Motivation: conformance to the other
