- # Take first subdir (or a subdir specified in a file) and consider
- # it a git repo dir. Get its origin, exchange the last bit for
- # other project name and clone the other repo
- #
- # This is useful if you have a local dir where you store repos
- # for various projects from a common namespace that differ only
- # in last part of the remote URI. Now all you need to do to
- # clone new one is "git sibling aproject". The script will
- # do the rest for you including sniffing the URI.
- #
- # The script simply takes the first subdir. In case this is not
- # OK for you (e.g. the dir id likely to be empty or contain
- # come "non-compliant" repos, you can specify path to the
- # other "template" repo in .gittum-sibling file.
- #
- # Hint: regarding the "template" repo, you can easily create
- # a "fake" repo that would sit elsewhere, e.g.:
- # $ mkdir .some/hidden/dir
- # $ cd .some/hidden/dir
- # $ git init
- # $ git remote add origin ssh://our_server/projects/FAKE
