# You have to run on Ruby1.9.2(or 1.9.3) in rvm.

=begin
This script can run on ArchLinux-KDE.
1. Install rvm.
2. Install ruby 1.9.2 (or 1.9.3)
3. rvm use 1.9.2 (or 1.9.3) --default
4. Run this script.
(If you use 1.9.3-p0,you have to add to option '--rubyname=ruby-1.9.3-p0'.)

But,you should not trust 100% this script and me.
