  15 ### from the file `./configure.in'.
  16 ### To rebuild it, execute the command
  17 ###     autoconf

  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.

  98 #### Usage messages.
  99
 100 short_usage="Usage: ${progname} CONFIGURATION [-OPTION[=VALUE] ...]
 101
 102 Set compilation and installation parameters for GNU Emacs, and report.
 103 CONFIGURATION specifies the machine and operating system to build for.
 104 --with-x                Support the X Window System.
 105 --with-x=no             Don't support X.
 106 --with-x-toolkit        Use an X toolkit.
 107 --with-x-toolkit=no     Don't use an X toolkit.
 108 --with-gcc              Use GCC to compile Emacs.
 109 --with-gcc=no           Don't use GCC to compile Emacs.
 110 --x-includes=DIR        Search for X header files in DIR.
 111 --x-libraries=DIR       Search for X libraries in DIR.
 112 --run-in-place          Use libraries and data files directly out of the
 113                         source tree.
 114 --single-tree=DIR       Has the effect of creating a directory tree at DIR
 115                         which looks like:
 116                           .../DIR/bin/CONFIGNAME (emacs, etags, etc.)
 117                           .../DIR/bin/CONFIGNAME/etc (movemail, etc.)
 118                           .../DIR/common/lisp  (emacs' lisp files)
 119                           .../DIR/common/site-lisp (local lisp files)
 120                           .../DIR/common/lib (DOC, TUTORIAL, etc.)
 121                           .../DIR/common/lock (lockfiles)
 122 --srcdir=DIR            Look for the Emacs source files in DIR.
 123 --prefix=DIR            Install files below DIR. Defaults to \`${prefix}'.
 124
 125 You may also specify any of the \`path' variables found in Makefile.in,
 126 including --bindir, --libdir, --etcdir, --infodir, and so on.  This allows
 127 you to override a single default location when configuring.
 128
 129 If successful, ${progname} leaves its status in config.status.  If
 130 unsuccessful after disturbing the status quo, it removes config.status."
 131
 132
 133 #### Option processing.
 134
 135 ### Record all the arguments, so we can save them in config.status.
 136 arguments="$@"
 137
 138 ### Shell Magic: Quote the quoted arguments in ARGUMENTS.  At a later date,
 139 ### in order to get the arguments back in $@, we have to do an
 140 ###  `eval set x "$quoted_arguments"; shift'.
 141 quoted_arguments=
 142 for i in "$@"; do
 143    quoted_arguments="$quoted_arguments '$i'"
 144 done
 145
 146 ### Don't use shift -- that destroys the argument list, which autoconf needs
 147 ### to produce config.status.  It turns out that "set - ${arguments}" doesn't
 148 ### work portably.
 149 ### However, it also turns out that many shells cannot expand ${10} at all.
 150 ### So using an index variable doesn't work either.  It is possible to use
 151 ### some shell magic to make 'set x "$arguments"; shift' work portably.
