Making one gem of many

[Trans]

Any chance of getting RubyGems to support the packages/ dir that's
supported by setup.rb? I currently have to run a custom staging task
before I can create a gem for a project that has subprojects.

Alternatively, RubyGem multi-packages might be nice. Installing a
multi-package would install dependent packages, but would bevave as if
it were a single package.

Another though it to create a "GemCrusher" that could take a set of
gems and merge them into a single gem.

Thoughts?
