source: trunk/scripts/git-migration/git-migrate @ 1878

Last change on this file since 1878 was 1876, checked in by broder, 16 years ago

As a result of Greg's and my git-svn based moves, many of the package
directories ended up with a commit where every file in the repo was
committed. Punt that repo from the newly revised history.
