This module provides access to the Unix password database.
Password database entries are reported as 7-tuples containing the
following items from the password database (see `<pwd.h>'), in order:
pw_name, pw_passwd, pw_uid, pw_gid, pw_gecos, pw_dir, pw_shell. The
uid and gid items are integers, all others are strings. An exception
is raised if the entry asked for cannot be found.
