Module: CapistranoGitMethods

Defined in:
lib/capistrano-git-methods.rb

Overview

Extends the capistrano configuration, to allow the git namespace to be available within the capistrano recipe.

Requirements

This requires the current_path variable to be present. This should already be available in the standard capistrano deploy scheme.
