Is there a library equivalent of "rm -rf" ?

I couldn't find a library function to (recursifely) remove a directory
and everything in it.
os.rmdir removes a directory, but only if it's empty.
os.removedirs removes a file, then pruns empty directories above it.
Did I miss something?
The obvious question is: ``Why do I care? It's trivial to write.''
The answer is that it's not quite trivial in the presence of symbolic
links: If the function encounters a symbolic link, it should not
follow it even if it refers to a directory. So the obvious code,
which checks for a directory and traverses it if it gets one,
is wrong--and dangerously so.
