 The :mod:`glob` module finds all the pathnames matching a specified pattern
-according to the rules used by the Unix shell.  No tilde expansion is done, but
-``*``, ``?``, and character ranges expressed with ``[]`` will be correctly
-matched.  This is done by using the :func:`os.listdir` and
-:func:`fnmatch.fnmatch` functions in concert, and not by actually invoking a
-subshell.  Note that unlike :func:`fnmatch.fnmatch`, :mod:`glob` treats
-filenames beginning with a dot (``.``) as special cases.  (For tilde and shell
-variable expansion, use :func:`os.path.expanduser` and

 For a literal match, wrap the meta-characters in brackets.
