=head1 NAME
mason_handler.svc - Win32 IIS Service handler for RT
=head1 SYNOPSIS
perl mason_handler.svc --install # install as service
perl mason_handler.svc --deinstall # deinstall this service
perl mason_handler.svc --help # show this help
perl mason_handler.svc # launch handler from command line
=head1 DESCRIPTION
This script manages a stand-alone FastCGI server, and populates the necessary
registry settings to run it with Microsoft IIS Server 4.0 or above.
Before running it, you need to install the B<FCGI> module from CPAN, as well as
B<Win32::Daemon> from L<http://www.roth.net/perl/Daemon/> if you want to install
itself as a service.
This script will automatically create a virtual directory under the IIS root;
its name is taken from C<$WebPath> in the F<RT_Config.pm> file. Additionally,
please install the ISAPI binary from L<http://www.caraveo.com/fastcgi/> and set
up an ISAPI Script Map that maps F<.html> files to F<isapi_fcgi.dll>.
Once the service is launched (either via C<net start RTFastCGI> or by running
C<perl mason_handler.svc>), a FCGI server will start and bind to port C<8284>
(mnemonics: the ASCII value of C<R> and C<T>); the ISAPI handler's C<BindPath>
registry setting will also be automatically populated.
