Building Grendel:

Make sure you have the required (external) packages first.  

Then:
	./configure
	gmake

The 'configure' script will create the Makefiles with all necessary CLASSPATH
settings and such set up appropriately for your system. You no longer have to 
edit the Makefiles or set CLASSPATH manually.

'configure' will look for three specific Java compilers (in this order):
	1. 'javac-ea' - early access of next-generation Java compiler from
	   Java Software (Sun)

	2. 'javac' - standard Sun JDK compiler

	3. 'jikes' - IBM's Java-compatible compiler (included because some
	   people like to use it instead of 'javac')

'configure' will use whichever of these three it finds first as the compiler
for Grendel.

Running Grendel: 

There are currently two ways you can run Grendel:
	
1. Type 'java grendel.Main' (with the correct CLASSPATH, or you can 
	use the '-classpath' option to set the classpath on the 
	command-line)
2. Type 'make run' after building and watch it work.

Editing Makefiles:

Do not edit the generated Makefiles as they will be overwritten when you next
run 'configure' or 'configure.status'. If you want to change something in the
Makefiles, or add or delete targets, edit the Makefile.in files.

If you edit 'configure.in' you will need to run GNU autoconf to remake the 
'configure' script. If you don't have GNU autoconf and don't want to get it,
just don't go there.
