Oops, I was browsing the local docs *blush* . Use this link instead:

http://redshift.sourceforge.net/script/doc/index.html

Here's one way to handle your config.rb file:

$ cat config.rb
def tool_mysql; 'X:/mysql.exe'; end
TOOL_MYSQL = 'X:/mysql.exe'

$ cat main.rb
require 'script'

config = Script.load "config.rb"

puts config.tool_mysql
puts config::TOOL_MYSQL

$ ruby main.rb
X:/mysql.exe
X:/mysql.exe
