More conventional and easier to manage Gemspec

Gemspec files are simply Ruby files. So, I like to make a Gemspec file that can easily be copied and pasted into new projects and only need to change a few config options (name, version, description, summary, etc), and allow for all of the other options to be pragmatically gathered. 

Saves alot of time!

> Note: RubyGems adds the date and rubygems_version options at build time if it isn't included in the Gemspec and it is good practice to leave it out.

Cheers!
