author Eric Wing <ewing . public |-at-| gmail . com> Wed May 12 12:49:28 2010 -0700 (5 days ago) Added the automated test plist file and modified .hgignore to be less aggressive. Discovered that the new plist file for the automated test was not checked in because the .hgignore file was too aggressive. I changed the .hgignore to not ignore the Xcode directory and instead added a longer list of things to ignore.
