# Small utility to test "build area" that correct number of 
# IUs ae created for "tooling-type" IUs and "config-IUs". 
# TODO: should formalize in Java, and check repository directly? 
# TODO: may need adjustment to better check "MacApp" layout? 
# 3/21/2015 - did check to check for zero symbolic links (used to check 
# for 6, but now we no longer create them.
