Why do I love Debian? Coz of the package management system. Now Ruby has the same nice feature, called RubyGems

Install:

ruby install.rb

See what is available:

gem --remote --list

Search for the string Doom in descriptions:

gem --remote --search Doom

Install progressbar:

gem --remote --install progressbar

Now relax, have a good milkshake in the sun. A big big thanks to the developers: Rich Kilmer, Chad Fowler, David Black, Paul Brannan, Jim Weirch, Curt Hibbs, Gavin Sinclair, etc.
