I’ve got Ruby running on my palmtop, and I don’t want to waste the  
extra space with ri or RDoc documentation for certain gems. I did  
some hunting and couldn’t find a simple answer for my questions so I  
thought I’d ask here.

How can I do a “gem install” and _not_ generate that documentation?  
How would i “uninstall” certain already-installed documentation?  
(just find and delete it?)

I believe you can pass --no-rdoc and --no-ri to the gem command.

Try “gem help install”. It will list you all options including  
–no-rdoc and --no-ri as Rob mentioned them

Aha. I worked through some of the help system but misunderstood how  
to use it. I see what you’re talking about now, thanks.

So I guess I can uninstall the gems and then reinstall them without  
the documentation, and that should clean things up nicely.
