  21 # Shell script to edit files and make symlinks in preparation for
  22 # compiling Emacs.
  23 #
  24 # Usage: configure machine
  25 #
  26 # If configure succeeds, it leaves its status in config.status.
  27 # If configure fails after disturbing the status quo,
  28 #       config.status is removed.
  29 #
  30
  31 # Remove any leading "." elements from the path name.  If we don't
  32 # remove them, then another "./" will be prepended to the file name
  33 # each time we use config.status, and the program name will get larger
  34 # and larger.  This wouldn't be a problem, except that since progname
  35 # gets recorded in all the Makefiles this script produces,
  36 # move-if-changed thinks they're different when they're not.
  37 #
  38 # It would be nice if we could put the ./ in a \( \) group and then
  39 # apply the * operator to that, so we remove as many leading ./././'s
  40 # as are present, but some seds (like Ultrix's sed) don't allow you to
  41 # apply * to a \( \) group.  Bleah.

  47 Set compilation and installation parameters for GNU Emacs, and report.
  48 MACHINENAME is the machine to build for.  For example:
  49    ${progname} decstation
  50 configures Emacs to run on a DECstation running Ultrix.  See \`etc/MACHINES'.
  51 Options are:
  52   --with-x, --with-x11 or --with-x10 - what window system to use;
  53          default is to use X11 if present.  If you don't want X, specify
  54          \`--with-x=no'.
  55   -g, -O - Passed to the compiler.  Default is -g, plus -O if using gcc.
  56   --prefix=DIR - where to install Emacs's library files
  57   --libdir=DIR - where to look for arch-dependent library files
  58   --datadir=DIR - where to look for architecture-independent library files
  59   --bindir=DIR - where to install the Emacs executable, and some friends
  60   --lisppath=PATH - colon-separated list of Emacs Lisp directories
  61   --lockdir=DIR - where Emacs should do its file-locking stuff
  62 If successful, ${progname} leaves its status in config.status.  If
  63 unsuccessful after disturbing the status quo, config.status is removed."
  64 # These are omitted since users should not mess with them.
  65 #  --gnu-malloc=[yes] or no - use the GNU memory allocator
  66 #  --rel-alloc=[yes] or no - use compacting allocator for buffers
  67 #  --lisp-float-type=[yes] or no - Support floating point in Emacs Lisp.
  68 # --window-system is omitted because --with... follow the conventions.
