=head1 NAME

MasonX::Resolver::Multiplex - multiplex several Resolver objects

=head1 VERSION

Version 0.001

=head1 SYNOPSIS

  use MasonX::Resolver::Multiplex;

  my $resolver = MasonX::Resolver::Multiplex->new(
    resolvers => [
      My::Custom::Resolver->new,
      HTML::Mason::Resolver::File->new,
    ],
  );

  my $interp = HTML::Mason::Interp->new(
    resolver => $resolver,
    # ... other options
  )

=head1 DESCRIPTION

Use this Resolver subclass when you want to combine the behavior of other
Resolver subclasses, such as in the L</SYNOPSIS>.

This class delegates methods to its contained C<resolvers>.  Each method is
called on each resolver in order; the first to return a true value 'wins'.

Delegated methods:

=item * get_info
