In my working with the source I wanted to be able to recreate a new source tree.
I wrote a script that automates the instructions that Ray gives for downloading
and compiling the code. Also, the makefiles are written so that they reference
your home directory rather than your current directory. This requires you to
work in your home directory rather then some sub-directory. This precludes
having multiple build environments. This script had a fix for that.
I have attached the script below.
