Introduction to Gems

What is a Gem?

A gemstone is a piece of mineral crystal which, in cut and polished form, is used to make jewelry or other adornments.

But actually...

From RubyGems.org

The RubyGems software allows you to easily download, install, and use ruby software packages on your system.

The software package is called a “gem” which contains a packaged Ruby application or library.

Gems can be used to extend or modify functionality in Ruby applications.

A way of using another's code that is packaged nicely, that makes your life easier.
