packaging gem tests

[Ken Dreyer]

I'm wondering about how to handle things like the Rakefile, or /spec,
or /test directories in rubygem packages. My inclination is to leave
these out of the package to keep it slimmer, but I see that some
rubygems do include them in the package (or at least the -doc
subpackage). The example on the Ruby packaging guidelines also
includes these in -doc.

Are these files really that useful to ship to end users?
