[Catalyst] MasonSite helper for Mason view

I've spent the last day hacking together a Mason equivalent of the
TTSite helper. I think TTSite is useful; I hope this will be too.
The mini-site is my mix of the TTSite example, and
various practices outlined in the Mason Book and elsewhere. Rather than
require hand modifications to the Root controller, I've chosen to have
MasonSite create a MasonEG controller to demo the mini-site.
It should be sufficent to:
$ # install the patched Catalyst::View::Mason module first
$ catalyst.pl TryMasonSite
$ cd TryMasonSite/
$ ./script/trymasonsite_create.pl view Mason MasonSite
$ ./script/trymasonsite_server.pl
$ firefox http://localhost:3000/masoneg
I've also patched Catalyst::View::Mason to permit the Mason
allow_globals config option to be specified, augmenting it with $c,
$base and $name.
All of this is attached as a patch against Catalyst::View::Mason version
0.8.
I'd be delighted if people could try it and give me feedback. Assuming
no major howls, I'll also announce it on the Mason list.
Best

+
+Catalyst::Helper::View::MasonSite - Helper for Mason view which builds a
+skeleton web site
+
+=head1 SYNOPSIS
+
+ script/create.pl view Mason MasonSite
+
+=head1 DESCRIPTION
+
+This helper module creates a Mason View module, and also creates an
+simple Mason framework and example pages to get you started.
+
+The Mason framework is created under your project's F<root> directory
+within subdirectories F<system> and F<template>, and the example
+pages within subdirectory F<masoneg>. A controller called C<MasonEg>
+is also created, so that you can visit C</masoneg> to view the example
+pages when you run your Catalyst application.
