Uninstall everything in local repository of gem.

Hi, all

when i type command ‘gem list’ it will show me the list as the following:

*** LOCAL GEMS ***

abstract (1.0.0) actionmailer (3.0.9) actionpack (3.0.9) activemodel (3.0.9) activerecord (3.0.9) activeresource (3.0.9) activesupport (3.0.9) arel (2.0.10) builder (2.1.2) bundler (1.0.15) … …

So, i want to uninstall everything in the list , in other words, remove everything in local repository of gems, but i don’t want uninstall it one by one with that original command.
