  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
  35 ### Remove any leading "." elements from the path name.  If we don't
  36 ### remove them, then another "./" will be prepended to the file name
  37 ### each time we use config.status, and the program name will get larger
  38 ### and larger.  This wouldn't be a problem, except that since progname
  39 ### gets recorded in all the Makefiles this script produces,
  40 ### move-if-change thinks they're different when they're 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.

  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 --srcdir=DIR option specifies that the configuration and build
  68         processes should look for the Emacs source code in DIR, when
  69         DIR is not the current directory.  This option doesn't work yet.
  70
  71 If successful, ${progname} leaves its status in config.status.  If
  72 unsuccessful after disturbing the status quo, it removes config.status."
