Right...RUBYOPT would 'require "rubygems"' and then...

It actually now works across ANY file in ANY gem (in version sorted order).
So, as a developer, you just put your files in the lib dir of your gem (or
wherever) and then with the above mentioned RUBYOPT, you can just do:
And the new loadpath_manager searches all the gems for a file that matches
and then require_gem's that gem, then does a regular require of net/ssh.
This allows rubygems to be transparent. Basically think of it as merging
the lib paths of all the gems into one search space and finding based on
your require (like ruby itself does now across the LOAD_PATH).

Right, you need the CVS version of rubygems or wait until we release (SOON
SOON) 0.8.0. Its not 'ubygems'...that just allows the setting of:
