Most of os.path functionality is already provided.
os.path has the following functions:

  Function      Ruby equivalent
---------------+-------------------
  abspath       File::expand_path
  basename      File::basename
  commonprefix  *1
  dirname       File::dirname
  exists        File::exist?
  expanduser    File::expand_path
  expandvars    *2
  getatime      File::atime
  getmtime      File::mtime
  getsize       File::size
  isabs         *1
  isdir         File::directory?
  isfile        File::file?
  islink        File::symlink?
  ismount       *1
  join          File::join
  normcase      *3
  normpath      File::expand_path
  samefile      f.path == f.path
  sameopenfile  f.fileno = f.fileno
  samestat      File::Stat#== *4
  split         File::split
  splitdrive    *3
  splitext      File::basename
  stat          File::stat
  walk          Find::find
---------------+-------------------
        *1 not available, possible to provide in the future.
        *2 no plan to provide; Ruby has expression substitution.
        *3 Ruby file API is basically POSIX like; need discussion for
           system independent API.
        *4 File::Stat#== compares mtime only.

Hope this helps.
