The question I\'m really asking is why require does not take the name of the gem. Also, In the case that it doesn\'t, what\'s the easiest way to find the secret incantation
Watch source of gem and check lib directory. If there is no rb file then you must point to gem main rb file in subdirectory:
lib
rb
require 'dir/subdir/file'
for /lib/dir/subdir/file.rb.
/lib/dir/subdir/file.rb
