 __gitup__ (the _git-repo-updater_)

 gitup is a tool designed to pull to a large number of git repositories at once.
 It is smart enough to ignore repos with dirty working directories, and provides
 a (hopefully) great way to get everything up-to-date for those short periods of
 internet access between long periods of none.
 gitup is a tool designed to update a large number of git repositories at once.
 It is smart enough to handle multiple remotes, branches, dirty working

 gitup works on both OS X and Linux. You should have the latest version of git

 Want to update all git repositories in your current directory?
 Update all git repositories in your current directory:

    gitup .

 By default, gitup will fetch all remotes in a repository. Pass `--current-only`
 (or `-c`) to make it only fetch the remote tracked by the current branch.

 gitup will _merge_ upstream branches by default unless `pull.rebase` or
 `branch.<name>.rebase` is specified in git's config. Pass `--rebase` or `-r` to
 make it always _rebase_ (like doing `git pull --rebase=preserve`). Pass
 `--merge` or `-m` to make it always merge.

 For a list of all command arguments and abbreviations:

    gitup --help

 Finally, all paths can be either absolute (e.g. /path/to/repo) or relative
 (e.g. ../my/repo).
