Certain commands have a single record type:

    F

      release

    O

      checkout

    E

      export

    T

      rtag

One of five record types may result from an update:

    C

      A merge was necessary but collisions were  detected  (requiring
      manual merging).

    G

      A merge was necessary and it succeeded.

    U

      A working file was copied from the repository.

    P

      A working file was patched to match the repository.

    W

      The  working  copy of a file was deleted during update (because
      it was gone from the repository).

One of three record types results from commit:

    A

      A file was added for the first time.

    M

      A file was modified.

    R

      A file was removed.
