Beginning of new command parsing interface -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Beginning of new command parsing interface This adds commands.py, with a primary interface dispatch(args) Dispatch searches a table of known commands, handles switches, sets up a repo object if appropriate, and dispatches the command. It also handles KeyboardInterrupt and can handle similar exceptions in the future. If the command is unknown, it falls through to the current command handler. Commands currently handled by the new scheme: help, init, and annotate manifest hash: 134cd032c880985e3f92f82efb8b629dd862ba4c -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.0 (GNU/Linux) iD8DBQFCnXEGywK+sNU5EO8RAuDAAJ9q7K4w7qGVWv1NWjCPFGO/UJc6VQCdEhMQ sBBlSRzah9QPy8K94catZyg= =wuRf -----END PGP SIGNATURE-----
