Subject: gem API

I'm curious is there a flag or an easy way to extend gem when calling  
it from the command line to do the following:
remove lines such as:

  \n*** LOCAL GEMS ***\n\n
and
  \n*** REMOTE GEMS ***\n\n

and to control the output formatting of
gem list
or of
gem list -d
?

I'd like to get that output in a more manageable format, but without  
permanently altering gem.
I just want the easiest way to alter those methods when calling gem  
or calling gem via ruby at the command line...
I don't want to break any body's gem tool, but I do want to use gem's  
output for list.

I suppose I'll need to include a file to use as an argument...
ruby -rubygems filename.rb

What I am doing is building a gui wrapper in Cocoa on OS X for common  
gem commands.
I want to later add gem install and gem uninstall, but I'm not sure  
what the best way would be to handle gems that have more involved  
install/uninstall processes, such as when the user is prompted for [y/ 
n]? input on whether to include a dependency or something in that  
install/uninstall process.
Is there a consistent thing I should look for in this or some API I  
can dig into?
Same goes for gems that on install ask for such things as platform  
choice (the mysql gem is an example of this).
