=head1 NAME

Apache::AxKit::MediaChooser::WAPCheck - WAP device media chooser

=head1 SYNOPSIS

  AxAddPlugin Apache::AxKit::MediaChooser::WAPCheck

=head1 DESCRIPTION

This module sets the preferred media type in AxKit to B<handheld> if
it detects that a WAP device made the request. This way you can specify
different stylesheets for WAP devices automatically.

The selection is performed either based on the C<Accept> header being
sent, or based on the C<User-Agent> header (see the source code for
a list of the supported user agent strings).
