Hi Luis,

This is the script I use. It strips down the c:\ruby directory from 179
MB to 51 MB on my computer, and apparently, everything works. It is
still very big, but acceptable, especially when compressed in RAR: 14.3
MB.

------------------------------------------------------------
$OLD_PATH = 'c:\\ruby'
$NEW_PATH = 'c:\\ruby_stripped'

require 'fileutils'

FileUtils.rm_rf($NEW_PATH)
FileUtils.mkdir($NEW_PATH)
FileUtils.cp_r($OLD_PATH + '\\bin', $NEW_PATH + '\\bin')
FileUtils.cp_r($OLD_PATH + '\\lib', $NEW_PATH + '\\lib')
FileUtils.rm_rf($NEW_PATH + '\\lib\\ruby\\gems\\1.8\\doc')
------------------------------------------------------------

If anyone is able to strip down the c:\ruby directory for deployment
even more, your help is welcome!

Regards,

Philippe
