NAME

       Verilog::Netlist::Subclass - Common routines for all classes

SYNOPSIS

         package Verilog::Netlist::Something;
         use Verilog::Netlist::Subclass;
         use base qw(Verilog::Netlist::Subclass);

         ...

         $self->info("We're here\n");
         $self->warn("Things look bad\n");
         $self->error("Things are even worse\n");
         $self->exit_if_error();

DESCRIPTION

       The Verilog::Netlist::Subclass is used as a base class for all Verilog::Netlist::*
       structures.  It is mainly used so that $self->warn() and $self->error() will produce
       consistent results.

       $self->errors()
           Return number of errors detected.

       $self->userdata (key) =item $self->userdata (key, data)
           Sets (with two arguments) or retrieves the specified key from an opaque hash.  This
