"""This module contains the SVNCommit classes.
There are five types of SVNCommits:
SVNInitialProjectCommit -- Initializes a project (creates its trunk,
branches, and tags directories).
SVNPrimaryCommit -- Commits one or more CVSRevisions on one or more
lines of development.
SVNBranchCommit -- Creates or fills a branch; that is, copies files
from a source line of development to a target branch.
SVNTagCommit -- Creates or fills a tag; that is, copies files from a
source line of development to a target tag.
SVNPostCommit -- Updates trunk to reflect changes on a non-trunk
default branch.
