=for position DESCRIPTION

=head1 DESCRIPTION

B<Glib::KeyFile> lets you parse, edit or create files containing groups of
key-value pairs, which we call key files for lack of a better name. Several
freedesktop.org specifications use key files now, e.g the Desktop Entry
Specification and the Icon Theme Specification.

The syntax of key files is described in detail in the Desktop Entry
Specification, here is a quick summary: Key files consists of groups of
key-value pairs, interspersed with comments.

=head1 METHODS

=head2 keyfile = Glib::KeyFile-E<gt>B<new> 

=head2 boolean = $key_file->B<get_boolean> ($group_name, $key)

=over

=item * $group_name (string) 

=item * $key (string) 

=back

Retrieves a boolean value from $key inside $group_name.

May croak with a L<Glib::Error> in $@ on failure.

=head2 list = $key_file->B<get_boolean_list> ($group_name, $key)

=over

=item * $group_name (string)

=over

=item * $group_name (string) 

=item * $key (string) 

=item * ... (list) list of booleans

=back

Sets a list of booleans in $key inside $group_name.  If $key cannot be found
then it is created.  If $group_name cannot be found then it is created.
