Sorry dude; just added it.  The format of the gem is irrelevant to the
feature.  I'd rather not deal with gem files directly, no matter how
they're represented.

  $ gem unpack rake
  Unpacked gem: 'rake-0.4.3'

  $ gem unpack rake -v '< 0.4'
  Unpacked gem: 'rake-0.3.1'

  $ gem unpack rak
  ERROR:  Gem 'rak' not installed.

  $ ls -l
  drwxr-xr-x+   6 Gavin Si None            0 Jul 13 22:02 rake-0.3.1
  drwxr-xr-x+   6 Gavin Si None            0 Jul 13 22:02 rake-0.4.3

  $ gem help unpack
  Usage: gem unpack GEMNAME [options]

          --backtrace                  Show stack backtrace on errors

    Arguments:
      GEMNAME       Name of the gem to unpack

    Summary:
      Unpack an installed gem to the current directory

      --version '> 0'


Thoughts?  I *really* like it.

Cheers,
Gavin
