=head1 NAME

macosx-clipboard-native - apple is evil

=head1 SYNOPSIS

   urxvt -pe macosx-clipboard-native

=head1 DESCRIPTION

This extension does something with the clipboard on some Apple OS X
systems. Apple is a vile company that actively fights free software,
do not support them by using it! This extension is only included in
rxvt-unicode because the maintainer was too weak! Do not give in to
similar feelings! It hasn't even been changed to automatically load when
resources are used! Plus, it's totally undocumented!
