HTTParty, Awesome_nested_set, rdoc option(s)

For those who wanna use HTTParty well with RoR, you can follow this link: HTTParty.

Talking about listing data as Tree and easy to search, I would like to present you about awesome_nested_set which is cool.

It was not bad that some guys don't know how to generate their Rdoc as the whole structure after they generate it first time because they don't delete the doc folder when they wanna generate it as the whole again.
To generate your RDoc without some specific folders or files you need to type as bellow:

rdoc --exclude folder1 --exclude folder2 --exclude folder3
