=head1 NAME

Module::Build::Platform::MacOS - Builder class for MacOS platforms

=head1 DESCRIPTION

The sole purpose of this module is to inherit from
C<Module::Build::Base> and override a few methods. Please see
L<Module::Build> for the docs.

=head2 Overridden Methods

=over 4

=item new()

MacPerl doesn't define $Config{sitelib} or $Config{sitearch} for some
reason, but $Config{installsitelib} and $Config{installsitearch} are
there. So we copy the install variables to the other location

=item make_executable()

On MacOS we set the file type and creator to MacPerl so it will run
with a double-click.

=item dispatch()

Because there's no easy way to say "./Build test" on MacOS, if
dispatch is called with no arguments and no @ARGV a dialog box will
pop up asking what action to take and any extra arguments.

Default action is "test".

=item ACTION_realclean()

Need to unlock the Build program before deleting.
