Ape Base Compile System

"The Ape Base Compile System is a set of bash scripts to leverage both ESP EPM (http://www.epmhome.org/) and MREPO (http://dag.wieers.com/home-made/mrepo/) in maintaining Red Hat based systems that require custom and secluded binaries. If you need "Ape" to be an acronym, then go for "Application Packaging Environment" as christened by Mark Stokan. The original notion for the name was that this system was "aping" the performance of several tasks."
