All you need to do is export a 'blog' method from your
MyApp::Plugin::Blog plugin.  This can be done quite easily using the
Exporter module.  Here is a quick example of what you would put in
your plugin:

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

require Exporter;

@ISA = qw(Exporter);
@EXPORT = qw(blog);

sub blog {
  blog blog blog
}

This all works through the 'import' method that is always called when
you 'use' a module.  For more details on exporting functions, see the
docs for Exporter, as well as perlfunc and perlmod.

Cheers,

Cees
