Subject: How to get a file contained in a gem "lib" directory?

Hi, I've build a gem "mylib" which contains a file called "myfile.xml" under 
"lib/mylib" dir. Let's imagine that depending on the environment it is stored 
(after installed) in:

  /usr/local/lib/ruby1.9/gems/1.9/gems/mylib-1.0.1/lib/mylib/myfile.xml

But of course there could be different versions of the gem:

  /usr/local/lib/ruby1.9/gems/1.9/gems/mylib-1.0.0/lib/mylib/myfile.xml
  /usr/local/lib/ruby1.9/gems/1.9/gems/mylib-1.0.1/lib/mylib/myfile.xml

Then I write a program which does:

  require "mylib"

so the latest version (1.0.1) is loaded.

How would I get "myfile.xml" for the loaded "mylib" gem version? I'm looking 
for a Gem class method like "Gem.bin_path(gemname)" but I cannot find it.

Thanks a lot.
