- <<-EOF
-The lock command will generate a list of +gem+ statements that will lock down
-the versions for the gem given in the command line. It will specify exact
-versions in the requirements list to ensure that the gems loaded will always
-be consistent. A full recursive search of all effected gems will be
-generated.
-
-Example:
-
- gemlock rails-1.0.0 > lockdown.rb
-
-will produce in lockdown.rb:
-
- require "rubygems"
- gem 'rails', '= 1.0.0'
- gem 'rake', '= 0.7.0.1'
- gem 'activesupport', '= 1.2.5'
- gem 'activerecord', '= 1.13.2'
- gem 'actionpack', '= 1.11.2'
- gem 'actionmailer', '= 1.1.5'
- gem 'actionwebservice', '= 1.0.0'
-
-Just load lockdown.rb from your application to ensure that the current
-versions are loaded. Make sure that lockdown.rb is loaded *before* any
-other require statements.
-
-Notice that rails 1.0.0 only requires that rake 0.6.2 or better be used.
-Rake-0.7.0.1 is the most recent version installed that satisfies that, so we
-lock it down to the exact version.
