RubyGems
RubyGems is a package manager for the Ruby programming language that provides a standard format for distributing Ruby programs and libraries (in a self-contained format called a "gem"), a tool designed to easily manage the installation of gems, and a server for distributing them. RubyGems was created around November 2003 and is now part of the standard library from Ruby version 1.9.
Gems
Gems are packages similar to Ebuilds. They contain package information along with files to install.
Gems are usually built from ".gemspec" files, which are YAML files containing information on Gems. However, Ruby code may also build Gems directly. Such a practice is usually used with Rake.
gem command
The gem command is used to build, upload, download, and install Gem packages.
gem usage
RubyGems is very similar to apt-get, portage, yum and npm in functionality.

Gemstone
A gemstone or gem (also called a fine gem, jewel, or a precious or semi-precious stone) is a piece of mineral crystal, which, in cut and polished form, is used to make jewelry or other adornments. However, certain rocks (such as lapis lazuli) or organic materials that are not minerals (such as amber or jet), are also used for jewelry, and are therefore often considered to be gemstones as well. Most gemstones are hard, but some soft minerals are used in jewelry because of their luster or other physical properties that have aesthetic value. Rarity is another characteristic that lends value to a gemstone. Apart from jewelry, from earliest antiquity engraved gems and hardstone carvings, such as cups, were major luxury art forms. A gem maker is called a lapidary or gemcutter; a diamond worker is a diamantaire.
The carvings of Carl Fabergé are significant works in this tradition.
Characteristics and classification
Gem (automobile)
The Gem was an automobile manufactured in both Jackson, Michigan and Grand Rapids, Michigan by the Gem Motor Car Company from 1917 to 1919. The company was incorporated in December, 1917, and early the next month it was announced that capitalization was to be $250,000, with $150,000 yet to be issued. The Gem was a light, assembled car with a four-cylinder G.B.&S. engine. Originally the plan was to acquire the complete chassis (from the Pontiac Chassis Company) and bodies (perhaps from Hayes) and complete the assembly of the cars in Grand Rapids. Gem planned to make some of the components itself eventually, though this appears not to have occurred. Only two models were produced, a 5-passenger touring car, selling for $845, and a light delivery van.

Gem
by: Zoot WomanCross the road to meet me
Thought you'd never see
You opened up my mind so
I'm waiting to believe
Audition all emotion
Never follow doubt
Show me one direction
I cannot be without
Heard enough to reason
Muted every sence
Through the interference
I'm ready to recieve
A glimmer of white promise
Found in you a gem
Call my intuition
I'm ready to believe
