# This is a script for archiving old private repos into an `attic` repo. To use, fill in the `ACCOUNT`
# variable below, then add this script to your "attic" repo, then just `./ [reponame]` from
# your cloned attic repo. This will take the contents of "reponame" and copy them into a subdirectory in
# attic named "reponame", preserving history. Note that the original repo is not modified in any way

# repo, so if it all goes horribly wrong, it's very easy to recover.
