use vars qw($VERSION @ISA @EXPORT @EXPORT_OK);

require Exporter;

@ISA = qw(Exporter AutoLoader);

# Items to export into callers namespace by default. Note: do not export

# names by default without a very good reason. Use EXPORT_OK instead.

# Do not simply export all your public functions/methods/constants.

@EXPORT = qw(

$VERSION = '0.01';

# Preloaded methods go here.

# Autoload methods go after =cut, and are processed by the autosplit program.
