+Javascript files are concatenated together in order, and minimized.  The

+CSS files are handled likewise, except that the name is bundleName.timestamp/bundleName.css.

+Other files are copied from their current location into the timestamped bundle directory.

+Older timestamped build directories are removed.

+occur during the build, then the old build directory is not affected and
