+=head1 NAME
+
+Bugzilla::Auth::Login - Gets username/password data from the user.
+
+=head1 DESCRIPTION
+
+Bugzilla::Auth::Login is used to get information that uniquely identifies
+a user and allows us to authorize their Bugzilla access.
+
+It is mostly an abstract class, requiring subclasses to implement
+most methods.
+
+Note that callers outside of the C<Bugzilla::Auth> package should never
+create this object directly. Just create a C<Bugzilla::Auth> object
+and call C<login> on it.
+
+=head1 LOGIN METHODS
+
+These are methods that have to do with getting the actual login data
+from the user or handling a login somehow.
+
+These methods are abstract -- they MUST be implemented by a subclass.

+
+=item C<get_login_info()>
+
+Description: Gets a username/password from the user, or some other
+             information that uniquely identifies them.
+Params:      None
+Returns:     A C<$login_data> hashref. (See L<Bugzilla::Auth> for details.)
+             The hashref MUST contain: C<user_id> *or* C<username>
+             If this is a login method that requires verification,
+             the hashref MUST contain C<password>.
+             The hashref MAY contain C<realname> and C<extern_id>.
+
+=item C<fail_nodata()>
+
+Description: This function is called when Bugzilla doesn't get
+             a username/password and the login type is C<LOGIN_REQUIRED>
+             (See L<Bugzilla::Auth> for a description of C<LOGIN_REQUIRED>).
+             That is, this handles C<AUTH_NODATA> in that situation.
+
+             This function MUST stop CGI execution when it is complete.
+             That is, it must call C<exit> or C<ThrowUserError> or some
+             such thing.
+Params:      None
+Returns:     Never Returns.

+methods that return either C<true> or C<false>.
