  35
  36 ### Since Emacs has configuration requirements that autoconf can't
  37 ### meet, this file is an unholy marriage of custom-baked
  38 ### configuration code and autoconf macros.
  39 ###
  40 ### We use the m4 quoting characters [ ] (as established by the
  41 ### autoconf system) to include large sections of raw sewage - Oops, I
  42 ### mean, shell code - in the final configuration script.
  43 ###
  44 ### Usage: configure config_name
  45 ###
  46 ### If configure succeeds, it leaves its status in config.status.
  47 ### If configure fails after disturbing the status quo,
  48 ###     config.status is removed.
  49
  50 ### Remove any more than one leading "." element from the path name.
  51 ### If we don't remove them, then another "./" will be prepended to
  52 ### the file name each time we use config.status, and the program name
  53 ### will get larger and larger.  This wouldn't be a problem, except
  54 ### that since progname gets recorded in all the Makefiles this script
  55 ### produces, move-if-change thinks they're different when they're
  56 ### not.
  57 ###
  58 ### It would be nice if we could put the ./ in a \( \) group and then
  59 ### apply the * operator to that, so we remove as many leading ./././'s
  60 ### as are present, but some seds (like Ultrix's sed) don't allow you to
  61 ### apply * to a \( \) group.  Bleah.

  90 #### Usage messages.
  91
  92 short_usage="Usage: ${progname} CONFIGURATION [-OPTION[=VALUE] ...]
  93
  94 Set compilation and installation parameters for GNU Emacs, and report.
  95 CONFIGURATION specifies the machine and operating system to build for.
  96 --with-x                Support the X Window System.
  97 --with-x=no             Don't support X.
  98 --x-includes=DIR        Search for X header files in DIR.
  99 --x-libraries=DIR       Search for X libraries in DIR.
 100 --with-gcc              Use GCC to compile Emacs.
 101 --with-gcc=no           Don't use GCC to compile Emacs.
 102 --run-in-place          Use libraries and data files directly out of the
 103                         source tree.
 104 --single-tree=DIR       Has the effect of creating a directory tree at DIR
 105                         which looks like:
 106                           .../DIR/bin/CONFIGNAME (emacs, etags, etc.)
 107                           .../DIR/bin/CONFIGNAME/etc (movemail, etc.)
 108                           .../DIR/common/lisp  (emacs' lisp files)
 109                           .../DIR/common/site-lisp (local lisp files)
 110                           .../DIR/common/lib (DOC, TUTORIAL, etc.)
 111                           .../DIR/common/lock (lockfiles)
 112 --srcdir=DIR            Look for the Emacs source files in DIR.
 113 --prefix=DIR            Install files below DIR. Defaults to \`${prefix}'.
 114
 115 You may also specify any of the \`path' variables found in Makefile.in,
 116 including --bindir, --libdir, --etcdir, --infodir, and so on.  This allows
 117 you to override a single default location when configuring.
 118
 119 If successful, ${progname} leaves its status in config.status.  If
 120 unsuccessful after disturbing the status quo, it removes config.status."

 123 #### Option processing.
 124
 125 ### Record all the arguments, so we can save them in config.status.
 126 arguments="$@"
 127
 128 ### Shell Magic: Quote the quoted arguments in ARGUMENTS.  At a later date,
 129 ### in order to get the arguments back in $@, we have to do an
 130 ###  `eval set x "$quoted_arguments"; shift'.
 131 quoted_arguments=
 132 for i in "$@"; do
 133    quoted_arguments="$quoted_arguments '$i'"
 134 done
 135
 136 ### Don't use shift -- that destroys the argument list, which autoconf needs
 137 ### to produce config.status.  It turns out that "set - ${arguments}" doesn't
 138 ### work portably.
 139 ### However, it also turns out that many shells cannot expand ${10} at all.
 140 ### So using an index variable doesn't work either.  It is possible to use
 141 ### some shell magic to make 'set x "$arguments"; shift' work portably.

 428 ### You would hope that you could choose an m/*.h file pretty much
 429 ### based on the machine portion of the configuration name, and an s-
 430 ### file based on the operating system portion.  However, it turns out
 431 ### that each m/*.h file is pretty manufacturer-specific - for
 432 ### example, apollo.h, hp9000s300.h, mega68k, news.h, and tad68k are
 433 ### all 68000 machines; mips.h, pmax.h, and news-risc are all MIPS
 434 ### machines.  So we basically have to have a special case for each
 435 ### configuration name.
 436 ###
 437 ### As far as handling version numbers on operating systems is
 438 ### concerned, make sure things will fail in a fixable way.  If
 439 ### /etc/MACHINES doesn't say anything about version numbers, be
 440 ### prepared to handle anything reasonably.  If version numbers
 441 ### matter, be sure /etc/MACHINES says something about it.

 443 ### Eric Raymond says we should accept strings like "sysvr4" to mean
 444 ### "System V Release 4"; he writes, "The old convention encouraged
 445 ### confusion between `system' and `release' levels'."
