Include the latest tree changes in the current patch. This command
generates a new GIT commit object with the patch details, the previous
one no longer being visible. The patch attributes like author,
committer and description can be changed with the command line
options. The '--force' option is useful when a commit object was
created with a different tool but the changes need to be included in
the current patch."""
