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

  67 #### Usage messages.
  68
  69 short_usage="Usage: ${progname} CONFIGURATION [-OPTION[=VALUE] ...]
  70
  71 Set compilation and installation parameters for GNU Emacs, and report.
  72 CONFIGURATION specifies the machine and operating system to build for.
  73 --with-x                Support the X Window System.
  74 --with-x=no             Don't support X.
  75 --x-includes=DIR        Search for X header files in DIR.
  76 --x-libraries=DIR       Search for X libraries in DIR.
  77 --with-gcc              Use GCC to compile Emacs.
  78 --with-gcc=no           Don't use GCC to compile Emacs.
  79 --run-in-place          Use libraries and data files directly out of the
  80                         source tree.
  81 --srcdir=DIR            Look for source in DIR.
  82 --prefix=DIR            Install files below dir.
  83
  84 If successful, ${progname} leaves its status in config.status.  If
  85 unsuccessful after disturbing the status quo, it removes config.status."
