dokipen / adding_git_svn_branches_by_hand.txt
Created April 20, 2010 18:49
git-svn fetch madness
Sometimes, when adding a branch like so:
`fetch = path/to/branch:refs/remotes/git-svn/mynewbranch`
the path to the branch is mispelt.
You then go ahead and do a `$ git svn fetch` and git finds nothing. You realize what an incredible dolt you are and fix the path,
`fetch = realpath/to/branch:refs/remotes/git-svn/mynewbranch`

# This increments all backup numbers and deletes or moves the last one
# to a monthly backup depending on the date.
#
# WARNING: This code breaks badly if you try and backup to dirs with the
# same basename! There is no safety mechanism.
