= giternal

== DESCRIPTION:

Giternal provides dead-simple management of external git
dependencies. It only stores a small bit of metadata, letting you
actively develop in any of the repos. Come deploy time, you can easily
freeze freeze all the dependencies to particular versions

== SYNOPSIS:

In your project root, create a file called config/giternal.yml. This
file should contain a list of externals in the following format:

name:
repo: git://url/to/repo.git
path: local/path/dir

For example, to add the rspec and rspec-rails plugins to your project,
add the following to config/giternal.yml

rspec:
repo: git://github.com/dchelimsky/rspec.git
path: vendor/plugins
rspec-rails:
repo: git://github.com/dchelimsky/rspec-rails.git
path: vendor/plugins

Now in project root, run 'giternal update' to update all of your
git dependencies.

== FREEZING AND UNFREEZING:

Sometimes you want to freeze your dependencies, e.g. when deploying.
This lets you create a self-contained deploy tag with all externals at
a known, working version. giternal will tar up the .git history dir
for each external, and then add the external to your git index. You
can review all the changes before committing.

giternal freeze

Unfreezing, as you might guess, is the opposite of freezing. It will
remove your external dir from the git index, and extract each
external's .git dir, restoring the history and allowing you to commit
or fetch changes.

== NOTES:

* You're probably using git for your own version control...and if so,
you need to add the giternal'd paths to .gitignore. You don't want
to check them into version control!!

* Deploying with vlad or capistrano simply requires you to run
'giternal update' after the code has been checked out, if your
externals are not frozen. If deploying a codebase with frozen
externals, there's nothing to do.

== INSTALL:

* sudo gem install giternal
