## Usage messages.

short_usage="Usage: ${progname} [--with-LIBS=dir] ...

Set compilation and installation parameters for RLaB.
--with-LIBS=DIR        Add DIR to list of directories to search for
            ALL libraries.
--with-NALIBS=DIR    Search for Numerical Analysis libraries in DIR.
--with-FLIBS=DIR    Search for Fortran libraries in DIR.
--with-PLIBS=DIR    Search for PLPLOT Library in DIR
--with-gcc        Force usage of the GNU C compiler.
--with-cc        Force usage of cc(1)
--prefix=DIR        Set the Makefile variable \'prefix\' to DIR.
            RLaB will be installed with DIR as the root
            directory.

If successful, ${progname} leaves its status in config.status.  If
unsuccessful after disturbing the status quo, it removes config.status."
