Usage: ${progname} [-arch=ARCH_TYPE]
                   [-prefix=INSTALL_DIR]  
          	   [-cc=C_COMPILER]
                   [-opt=OPTFLAGS] [-make=MAKEPGM]
where
   ARCH_TYPE    = the type of machine that wrappergen is to be configured for
   INSTALL_DIR  = directory where wrappergen will be installed (optional)
   OPTFLAGS     = optimization flags to give the compilers (e.g. -g)
   MAKEPGM      = version of make to use
                  
One and only one 'arch', and 'prefix' argument should be provided.

The option '-opt' allows you to specify options for the C compiler
For example, '-opt=-O' chooses optimized code generation on many
systems.

The option -make may be used to select an alternate make program.  For
example, on FreeBSD systems, -make=gnumake may be required because of bugs in
the system make.

Sample Configure Usage:

To make for running on sun4's running SunOS and with the installation 
directory equal to the current directory:

  ./configure -arch=sun4 
  make 

Known architectures include
                  sun4      (SUN OS 4.x)
                  solaris   (Solaris; probably 2.x)
                  hpux      (HP UX)
                  rs6000    (AIX for IBM RS6000)
                  sgi       (Silicon Graphics IRIX 5.x or 6.x)
                  IRIX      (synonym for sgi)
                  meiko     (Meiko CS2)
                  CRAY      (CRAY XMP, YMP, C90)

         
Others may be recognized.
