first, update to current HEAD:
git svn rebase
then, look for the appropriate hash-name in git corresponding to the svn-revision:
git log | grep -C 5 “my-desired-revision”
switching to the revision is done by a checkout:
git co f914a51a99f09aa609f253fb24a5adcfe0014461
then, do your work, e.g. compiling…
to switch back, clean up the changes caused by your work:
git clean -df
git reset —hard
final step is to switch to the “master” branch, which contains the HEAD revision:
git co master
