=head1 NAME

HTML::Mason::Utils - Publicly available functions useful outside of Mason

=head1 DESCRIPTION

The functions in this module are useful when you need to interface
code you have written with Mason.

=head1 FUNCTIONS

=over 4

=item data_cache_namespace ($comp_id)

Given a component id, this method returns its default
C<Cache::Cache> namespace.  This can be useful if you want to access
the cached data outside of Mason.

With a single component root, the component id is just the component
path. With multiple component roots, the component id is
C<key>/C<path>, where C<key> is the key corresponding to the root that
the component falls under.

=item cgi_request_args ($cgi, $method)

This function expects to receive a C<CGI.pm> object and the request
method (GET, POST, etc).  Given these two things, it will return a
hash in list context or a hashref in scalar context.  The hash(ref)
will contain all the arguments passed via the CGI request.  The keys
will be argument names and the values will be either scalars or array
references.
