configure

#!/bin/bash
# Filename:	configure
# Purpose:	Configures the system for compiling the Virtual AGC software
#		suite, allowing optional selection of the installation directory.
# Mod history:	05/14/04 RSB	Added --help and --prefix command-line options.
#		05/08/04 RSB	Cleaned up some cache issues.
#		05/28/05 RSB	Added yaDEDA.
#		07/16/05 RSB	Oops!  Fixed the removal of cache files.
#		08/06/05 RSB	Changed the default PREFIX used in MacOS X,
#				to avoid having to use it as a command-line parameter.

# We really don't have a GNU configure (except for those programs we've built with
# GLADE), but there are some things it's helpful to do or find out before running
# 'make', so we do it with this special script.  Yes, I suppose we really could
# use a GNU configure script, except that I've never figured out how to make
# one work under Win32.  Of course, this script doesn't work under Win32, either,
# so what kind of reasoning is that?  (It's called the "Chewbacca defense".)
