iwarshak / gemset

A simple, and somewhat naive gem installer that is very concerned about gem 
dependencies and version requirements

Given a list of gems, and versions of that gem, gemset will attempt
to install only the versions of gems that you requested. If that cannot be
fulfilled, it will fail, and nothing will be installed. 

For example, if you want package gem A version 1.0, and gem B version 2.0, 
but the gem spec for A specifies gem B version 1.5 as a dependency, then we
have a versioning conflict, and gemset will fail and nothing gets installed.

You can not specify a version of a gem, and gemset will pick the most appropriate
version so that all other dependencies are satisfied. 

The resolution is being done by wycats Bundler package.
