#### Usage messages.
short_usage="Usage: ${progname} CONFIGURATION [-OPTION[=VALUE] ...]
--with-gcc=no Don't use GCC to compile Emacs.
--run-in-place Use libraries and data files directly out of the
source tree.
---srcdir=DIR Look for source in DIR.
---prefix=DIR Install files below dir.
+--single-tree=DIR Has the effect of creating a directory tree at DIR
+ which looks like:
+ .../DIR/bin/CONFIGNAME (emacs, etags, etc.)
+ .../DIR/bin/CONFIGNAME/etc (movemail, etc.)
+ .../DIR/common/lisp (emacs' lisp files)
+ .../DIR/common/site-lisp (local lisp files)
+ .../DIR/common/lib (DOC, TUTORIAL, etc.)
+ .../DIR/common/lock (lockfiles)
+--srcdir=DIR Look for the Emacs source files in DIR.
+--prefix=DIR Install files below DIR. Defaults to \`${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."
