  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.

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

 120 If successful, ${progname} leaves its status in config.status.  If
 121 unsuccessful after disturbing the status quo, it removes config.status."

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

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

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