<<-EOF
The build command allows you to create a gem from a ruby gemspec.
The best way to build a gem is to use a Rakefile and the Gem::PackageTask
which ships with RubyGems.
The gemspec can either be created by hand or extracted from an existing gem
with gem spec:
$ gem unpack my_gem-1.0.gem
Unpacked gem: '.../my_gem-1.0'
$ gem spec my_gem-1.0.gem --ruby > my_gem-1.0/my_gem-1.0.gemspec
$ cd my_gem-1.0
[edit gem contents]
$ gem build my_gem-1.0.gemspec
