=head1 NAME

Catalyst::Restarter::Win32 - Uses Proc::Background to manage process restarts

=head1 DESCRIPTION

This class uses L<Proc::Background>, which in turn uses
L<Win32::Process>. The new process is run using the same command-line
as the original script, but without any restart-based options.

This is a big hack, but using forks just does not work on Windows.
