1. Make sure the following environment variable is set:
WinXP:
HOME=C:\Documents and Settings\*username*
Vista:
HOME=C:\Users\*username*
2. Create an .irbrc file in %HOME%:
$ cd %HOME%
$ touch .irbrc
If you don't have touch installed, use a good text editor to save the .irbrc. E Text Editor is good, as is Notepad++.
3. Install the following gems:
fastri
[http://eigenclass.org/hiki.rb?cmd=view&p=fastri&key=fastri]
map_by_method and what_methods
