unify checkout and resolve into update -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 unify checkout and resolve into update This replaces checkout and resolve with a single command: $ hg help co hg update [node] update or merge working directory If there are no outstanding changes in the working directory and there is a linear relationship between the current version and the requested version, the result is the requested version. Otherwise the result is a merge between the contents of the current working directory and the requested version. Files that changed between either parent are marked as changed for the next commit and a commit must be performed before any further updates are allowed. manifest hash: 513d285d7fb775d0560de49387042a685ea062f7 -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.0 (GNU/Linux) iD8DBQFComS7ywK+sNU5EO8RAmgRAJ96GA6qvHLy0Jp0fzUrR2os2azPuACePsdC YBldZtA7yIuTnV2vIbn7OSE= =QtM/ -----END PGP SIGNATURE-----
