+:mod:`glob` --- Unix style pathname pattern expansion
+=====================================================
+
+.. module:: glob
+ :synopsis: Unix shell style pathname pattern expansion.
+
+
+.. index:: single: filenames; pathname expansion
+
+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. (For tilde and shell variable expansion, use
+:func:`os.path.expanduser` and :func:`os.path.expandvars`.)
+
+
+.. function:: glob(pathname)
+
+ Return a possibly-empty list of path names that match *pathname*, which must be
+ a string containing a path specification. *pathname* can be either absolute
+ (like :file:`/usr/src/Python-1.5/Makefile`) or relative (like
+ :file:`../../Tools/\*/\*.gif`), and can contain shell-style wildcards. Broken
+ symlinks are included in the results (as in the shell).
+
+
+.. function:: iglob(pathname)
+
+ Return an iterator which yields the same values as :func:`glob` without actually
+ storing them all simultaneously.
+
+ .. versionadded:: 2.5
+
+For example, consider a directory containing only the following files:
+:file:`1.gif`, :file:`2.txt`, and :file:`card.gif`. :func:`glob` will produce
+the following results. Notice how any leading components of the path are
+preserved. ::
+
+ >>> import glob
+ >>> glob.glob('./[0-9].*')
+ ['./1.gif', './2.txt']
+ >>> glob.glob('*.gif')
+ ['1.gif', 'card.gif']
+ >>> glob.glob('?.gif')
+ ['1.gif']
