#### Configuration script for GNU Emacs
#### Copyright (C) 1992, 1994 Free Software Foundation, Inc.
### Don't edit this script!
### This script was automatically generated by the `autoconf' program

### To rebuild it, execute the command
### autoconf
### in the this directory. You must have autoconf version 1.7 or later.

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

#### Usage messages.
short_usage="Usage: ${progname} CONFIGURATION [-OPTION[=VALUE] ...]
Set compilation and installation parameters for GNU Emacs, and report.
CONFIGURATION specifies the machine and operating system to build for.
--with-x Support the X Window System.
--with-x=no Don't support X.
--with-x-toolkit Use an X toolkit.
--with-x-toolkit=no Don't use an X toolkit.
--with-gcc Use GCC to compile Emacs.
--with-gcc=no Don't use GCC to compile Emacs.
--x-includes=DIR Search for X header files in DIR.
--x-libraries=DIR Search for X libraries in DIR.
--run-in-place Use libraries and data files directly out of the
source tree.
--single-tree=DIR Has the effect of creating a directory tree at DIR
which looks like:
.../DIR/bin/CONFIGNAME (emacs, etags, etc.)
.../DIR/bin/CONFIGNAME/etc (movemail, etc.)
.../DIR/common/lisp (emacs' lisp files)
.../DIR/common/site-lisp (local lisp files)
.../DIR/common/lib (DOC, TUTORIAL, etc.)
.../DIR/common/lock (lockfiles)
--srcdir=DIR Look for the Emacs source files in DIR.
--prefix=DIR Install files below DIR. Defaults to \`${prefix}'.
You may also specify any of the \`path' variables found in Makefile.in,
including --bindir, --libdir, --etcdir, --infodir, and so on. This allows
you to override a single default location when configuring.
If successful, ${progname} leaves its status in config.status. If
unsuccessful after disturbing the status quo, it removes config.status."
#### Option processing.
### Record all the arguments, so we can save them in config.status.
arguments="$@"
### Shell Magic: Quote the quoted arguments in ARGUMENTS. At a later date,
### in order to get the arguments back in $@, we have to do an
### `eval set x "$quoted_arguments"; shift'.
quoted_arguments=
for i in "$@"; do
quoted_arguments="$quoted_arguments '$i'"
done
### Don't use shift -- that destroys the argument list, which autoconf needs
### to produce config.status. It turns out that "set - ${arguments}" doesn't
### work portably.
### However, it also turns out that many shells cannot expand ${10} at all.
### So using an index variable doesn't work either. It is possible to use
### some shell magic to make 'set x "$arguments"; shift' work portably.
