-The '%prog' command is ran to initialize a new GITC client for use
-with the GITC file system.
-
-This command will setup the client directory, initialize repo, just
-like repo init does, and then downloads the manifest collection
-and installs it in the .repo/directory of the GITC client.
-
-Once this is done, a GITC manifest is generated by pulling the HEAD
-SHA for each project and generates the properly formatted XML file
-and installs it as .manifest in the GITC client directory.
-
-The -c argument is required to specify the GITC client name.
-
-The optional -f argument can be used to specify the manifest file to
-use for this GITC client.
