  24 ### Shell script to edit files and make symlinks in preparation for
  25 ### compiling Emacs.
  26 ###
  27 ### Usage: configure config_name
  28 ###
  29 ### If configure succeeds, it leaves its status in config.status.
  30 ### If configure fails after disturbing the status quo,
  31 ###     config.status is removed.
  32
  33
  34 ### Remove any more than one leading "." element from the path name.
  35 ### If we don't remove them, then another "./" will be prepended to
  36 ### the file name each time we use config.status, and the program name
  37 ### will get larger and larger.  This wouldn't be a problem, except
  38 ### that since progname gets recorded in all the Makefiles this script
  39 ### produces, move-if-change thinks they're different when they're
  40 ### not.
  41 ###
  42 ### It would be nice if we could put the ./ in a \( \) group and then
  43 ### apply the * operator to that, so we remove as many leading ./././'s
  44 ### as are present, but some seds (like Ultrix's sed) don't allow you to
  45 ### apply * to a \( \) group.  Bleah.

  49 #### Usage messages.
  50
  51 short_usage="Type \`${progname} --usage' for more information about options."
  52
  53 long_usage="Usage: ${progname} CONFIGURATION [-OPTION[=VALUE] ...]
  54
  55 Set compilation and installation parameters for GNU Emacs, and report.
  56 CONFIGURATION specifies the machine and operating system to build for.
  57 For example:
  58         ${progname} sparc-sun-sunos4.1
  59 configures Emacs to build on a Sun Sparc machine running SunOS 4.1, and
  60         ${progname} decstation
  61 configures Emacs to run on a DECstation running Ultrix.  See \`etc/MACHINES'.
  62
  63 The --with-x, --with-x11 and --with-x10 options specify what window
  64         system to use; if all are omitted, use X11 if present.  If you
  65         don't want X, specify \`--with-x=no'.
  66
  67 The --x-includes=DIR option tells the build process where to search for
  68         the X Windows header files.  If this option is omitted, the
  69         build process assumes they exist in a directory the compiler
  70         checks by default.
  71
  72 The --x-libraries=DIR option tells the build process where to look for
  73         the X windows libraries.  If this option is omitted, the build
  74         process assumes they are in a directory the compiler checks by
  75         default.
  76
  77 The --with-gcc option says that the build process should use GCC to
  78         compile Emacs.  If you have GCC but don't want to use it,
  79         specify \`--with-gcc=no'.  \`configure' tries to guess whether
  80         or not you have GCC by searching your executable path, but if
  81         it guesses incorrectly, you may need to use this.
  82
  83 The --srcdir=DIR option specifies that the configuration and build
  84         processes should look for the Emacs source code in DIR, when
  85         DIR is not the current directory.  This option doesn't work yet.
  86
  87 If successful, ${progname} leaves its status in config.status.  If
  88 unsuccessful after disturbing the status quo, it removes config.status."
