Not right now, no. I've had a branch that adds a #meta hash to
Specification around for a while, but changing gemspec is fraught with
terror and I haven't been brave enough to merge it yet. :(
You can fake it with the current version of RubyGems by using
Gem#find_files and examining the paths that it returns. Keep in mind
that it looks through ALL available versions of all gems, as well as
the load path. Really really bad example off the top of my head:
# let's pretend all adhearsion components must have a
lib/adhearsion/component.txt file
component_gems = Gem.find_files("adhearsion/component.txt").
map { |f| %r|/([^/]+)/lib| =~ f && $1.split("-")[0..-2].join("-") }.uniq
