Why not simply use those of BSD ? Okay, the originate from Sun (due
to the comment at the start of the files) but you can basically do
what you want as long as the comment stays in the source file, so
could include those in the ruby distribution ? *shrug* I mean why
reinvent the wheel when usable code is out there.
