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

  96 #### Usage messages.
  97
  98 short_usage="Usage: ${progname} CONFIGURATION [-OPTION[=VALUE] ...]
  99
 100 Set compilation and installation parameters for GNU Emacs, and report.
 101 CONFIGURATION specifies the machine and operating system to build for.
 102 --with-x                Support the X Window System.
 103 --with-x=no             Don't support X.
 104 --with-x-toolkit        Use an X toolkit.
 105 --with-x-toolkit=no     Don't use an X toolkit.
 106 --with-gcc              Use GCC to compile Emacs.
 107 --with-gcc=no           Don't use GCC to compile Emacs.
 108 --x-includes=DIR        Search for X header files in DIR.
 109 --x-libraries=DIR       Search for X libraries in DIR.
 110 --run-in-place          Use libraries and data files directly out of the
 111                         source tree.
 112 --single-tree=DIR       Has the effect of creating a directory tree at DIR
 113                         which looks like:
 114                           .../DIR/bin/CONFIGNAME (emacs, etags, etc.)
 115                           .../DIR/bin/CONFIGNAME/etc (movemail, etc.)
 116                           .../DIR/common/lisp  (emacs' lisp files)
 117                           .../DIR/common/site-lisp (local lisp files)
 118                           .../DIR/common/lib (DOC, TUTORIAL, etc.)
 119                           .../DIR/common/lock (lockfiles)
 120 --srcdir=DIR            Look for the Emacs source files in DIR.
 121 --prefix=DIR            Install files below DIR. Defaults to \`${prefix}'.
 122
 123 You may also specify any of the \`path' variables found in Makefile.in,
 124 including --bindir, --libdir, --etcdir, --infodir, and so on.  This allows
 125 you to override a single default location when configuring.
 126
 127 If successful, ${progname} leaves its status in config.status.  If
 128 unsuccessful after disturbing the status quo, it removes config.status."
 129
 130
 131 #### Option processing.
 132
 133 ### Record all the arguments, so we can save them in config.status.
 134 arguments="$@"
 135
 136 ### Shell Magic: Quote the quoted arguments in ARGUMENTS.  At a later date,
 137 ### in order to get the arguments back in $@, we have to do an
 138 ###  `eval set x "$quoted_arguments"; shift'.
 139 quoted_arguments=
 140 for i in "$@"; do
 141    quoted_arguments="$quoted_arguments '$i'"
 142 done
 143
 144 ### Don't use shift -- that destroys the argument list, which autoconf needs
 145 ### to produce config.status.  It turns out that "set - ${arguments}" doesn't
 146 ### work portably.
 147 ### However, it also turns out that many shells cannot expand ${10} at all.
 148 ### So using an index variable doesn't work either.  It is possible to use
 149 ### some shell magic to make 'set x "$arguments"; shift' work portably.
