repo_tree maintains the exporter's state and provides a facility to to call fast_export, which writes objects to stdout suitable for consumption by fast-import. The exported functions roughly correspond to Subversion FS operations. . repo_add, repo_modify, repo_copy, repo_replace, and repo_delete update the current commit, based roughly on the corresponding Subversion FS operation. . repo_commit calls out to fast_export to write the current commit to the fast-import stream in stdout. . repo_diff is used by the fast_export module to write the changes for a commit. . repo_reset erases the exporter's state, so valgrind can be happy.
