Rubygems is kind enough to generate RDoc for installed gems, but the directories move as the gem versions evolve, and it's inconvenient to keep browsing for them. This tool produces a useful HTML index with direct links to the RDocs for all the gems installed on your system.
Getting it
The program's git repository is here: gemdocindex.
Either browse to 'gemdocindex' there and download the raw version, or check out ("clone") the repository as follows:
git clone git://git.sanityinc.com/gemdocindex.git
You can then track future changes by executing this command in the 'gemdocindex' directory:
git pull
Running it
Execute this command from a UNIX command line:
./gemdocindex > gemindex.html
(Windows users can probably run the same command, adding "ruby" at the beginning.)
Tested on OS X; should work on other platforms. Patches are welcome.

Thank you so much!
Very useful! I especially like the straightforward layout of the page, which is easier to scan than the one generated by the gem server.
Happy to hear it's helpful to you! I use it all the time. If you have any improvements/fixes etc., please let me know. It's on github too, BTW.
