=head1 NAME

pptemplate - script to generate Makefile.PL and PP file skeleton

=head1 SYNOPSIS

        # generate Makefile.PL and mymodule.pd in CWD
	pptemplate PDL::MyModule;


=head1 DESCRIPTION

The B<pptemplate> script is the easiest way to start a new module
for PDL that contains PP code (see also L<PDL::PP>). The usage is simply

  pptemplate modulename;

As a result pptemplate will generate a perl Makefile for the new
module (F<Makefile.PL>) that contains the minimal structure to
generate a module from PP code and also a skeleton file
for your new module.

The file will be called F<mymod.pd> if you called C<pptemplate> as

  pptemplate PDL::CleverAlgs::Mymod;

I suppose you can work out the naming rule C<;)>. If not resort to
experimentation or the source code.

C<pptemplate> will refuse to overwrite existing files of the same name
to avoid accidents. Move them out of the way if you really want to scrap
them.

=head2 Options

Currently there is only the C<-i> option which switches C<pptemplate>
into the so called I<internal mode>.  It should only be used when you
are starting a new module within the main PDL tree that is supposed to
be part of the PDL distribution and the normal PDL build process, e.g.

   cd PDL/IO;
   mkdir Mpthree; cd Mpthree;
   pptemplate -i PDL::IO::Mpthree;

=head1 BUGS

Maybe C<;)>.
Feedback and bug reports are welcome.
