#### Usage messages.
-short_usage="Type \`${progname} --usage' for more information about options."
-
-long_usage="Usage: ${progname} CONFIGURATION [-OPTION[=VALUE] ...]
+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.
-For example:
- ${progname} sparc-sun-sunos4.1
-configures Emacs to build on a Sun Sparc machine running SunOS 4.1, and
- ${progname} decstation
-configures Emacs to run on a DECstation running Ultrix. See \`etc/MACHINES'.
-
-The --with-x, --with-x11 and --with-x10 options specify what window
- system to use; if all are omitted, use X11 if present. If you
- don't want X, specify \`--with-x=no'.
-
-The --x-includes=DIR option tells the build process where to search
- for the X Windows header files. DIR should have a
- subdirectory called \`X11' which contains \`X.h', \`Xlib.h', and
- the rest of the header files; DIR should not contain \`X11'
- itself. If this option is omitted, the build process assumes
- they exist in a directory the compiler checks by default.
-
-The --x-libraries=DIR option tells the build process where to look for
- the X windows libraries. If this option is omitted, the build
- process assumes they are in a directory the compiler checks by
- default.
-
-The --with-gcc option says that the build process should use GCC to
- compile Emacs. If you have GCC but don't want to use it,
- specify \`--with-gcc=no'. \`configure' tries to guess whether
- or not you have GCC by searching your executable path, but if
- it guesses incorrectly, you may need to use this.
-
-The --srcdir=DIR option specifies that the configuration and build
- processes should look for the Emacs source code in DIR, when
- DIR is not the current directory. This option doesn't work yet.
+--with-x Support the X Window System.
+--with-x=no Don't support X.
+--x-includes=DIR Search for X header files in DIR.
+--x-libraries=DIR Search for X libraries in DIR.
+--with-gcc Use GCC to compile Emacs.
+--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.
If successful, ${progname} leaves its status in config.status. If
unsuccessful after disturbing the status quo, it removes config.status."
