+ <<-EOF
+The unpack command allows you to examine the contents of a gem or modify
+them to help diagnose a bug.
+
+You can add the contents of the unpacked gem to the load path using the
+RUBYLIB environment variable or -I:
+
+ $ gem unpack my_gem
+ Unpacked gem: '.../my_gem-1.0'
+ [edit my_gem-1.0/lib/my_gem.rb]
+ $ ruby -Imy_gem-1.0/lib -S other_program
+
+You can repackage an unpacked gem using the build command. See the build
+command help for an example.
