=head1 NAME

CP - Trick Configuration Processor

=head1 SYNOPSIS

CP [-defghmprsz?] [--debug] [--help] [-o I<outfile>] [--outfile=I<outfile>] 
[-v I<level>] [--verbose=I<level>] [--model_dirs]

=head1 DESCRIPTION

See the Trick User's guide for B<CP>

=head1 OPTIONS
   
=over 8

=item B<-e>

S_main_\${TRICK_HOST_CPU}.exe (Master executable)

=item B<-f>

Force CP to process S_define without catalog/cache

=item B<-g> | B<--debug>

Set the verbose level to 3

=item B<-h> | B<-?> | B<--help>

Print this help message

=item B<-m>

Makefile (Simulation make file)

=item B<-o> I<file_name> | B<--outfile>=I<outfile>

output all CP output to an external file

=item B<-p>

Create a simulation without python input processor.

=item B<-v> I<level> | B<--verbose>=I<level>

Set the verbose level.  Valid entries are 0-3.

=item B<-DTRICK_VER=x.x>

Note: -DTRICK_VER=x.x is automatically used when parsing header files and the S_define file
