[Wtr-general] Warnings: already initialized constant when executing watir scripts

[Charley Baker]

Ruby's require is case sensitive. Whether that's a good thing or not, it's
something to be aware of when requiring files. Require will load a file into
your ruby space once whether it's a ruby file or a dll or other binary
library, load is another method that will pull the file in everytime it's
called, and include is a way to pull in a namespace.

require 'watir'     # <- pull in watir.rb
include Watir    # <- add the Watir namespace defined in watir.rb as module
Watir
                       # so that now you can say ie = IE.new instead of
qualifying
                       # the module where IE lives -- Watir::IE

There are good descriptions of these basics in the Ruby pickaxe book:
http://www.rubycentral.com/book/tut_modules.html

and on the Ruby faq site:
