двунаправленная операция между репозиторием Subversion и Git (Bidirectional operation between a Subversion repository and Git)

$GIT_DIR/svn/**/.rev_map.*
Mapping between Subversion revision numbers and Git commit
names. In a repository where the noMetadata option is not
set, this can be rebuilt from the git-svn-id: lines that are
at the end of every commit (see the svn.noMetadata section
above for details).
git svn fetch and git svn rebase automatically update the
rev_map if it is missing or not up to date. git svn reset
automatically rewinds it.
