From 0455ec0330fd29146d6e16189cc9262566cc566d Mon Sep 17 00:00:00 2001 From: Aaron Crane Date: Sat, 6 Feb 2010 18:26:24 +0000 Subject: [PATCH] cvsimport: new -R option: generate .git/cvs-revisions mapping This option causes the creation or updating of a file mapping CVS (filename, revision number) pairs to Git commit IDs. This is expected to be useful if you have CVS revision numbers stored in commit messages, bug-tracking systems, email archives, and the like.
