NAME
       Pod::Simple::Debug -- put Pod::Simple into trace/debug
       mode

SYNOPSIS
        use Pod::Simple::Debug (5);  # or some integer

       Or:

        my $debuglevel;
        use Pod::Simple::Debug (\$debuglevel, 0);
        ...some stuff that uses Pod::Simple to do stuff, but which
         you don't want debug output from...

        $debug_level = 4;
        ...some stuff that uses Pod::Simple to do stuff, but which
         you DO want debug output from...

        $debug_level = 0;

DESCRIPTION
       This is an internal module for controlling the debug level
       (a.k.a. trace level) of Pod::Simple.  This is of interest
       only to Pod::Simple developers.

CAVEATS
       Note that you should load this module before loading
       Pod::Simple (or any Pod::Simple-based class).  If you try
       loading Pod::Simple::Debug after &Pod::Simple::DEBUG is
       already defined, Pod::Simple::Debug will throw a fatal
       error to the effect that "it's s too late to call
       Pod::Simple::Debug".

       Note that the "use Pod::Simple::Debug (\$x, somenum)" mode
       will make Pod::Simple (et al) run rather slower, since
       &Pod::Simple::DEBUG won't be a constant sub anymore, and
       so Pod::Simple (et al) won't compile with constant-
       folding.

GUTS
       Doing this:

         use Pod::Simple::Debug (5);  # or some integer

       is basically equivalent to:

         BEGIN { sub Pod::Simple::DEBUG () {5} }  # or some integer
         use Pod::Simple ();

       And this:

         use Pod::Simple::Debug (\$debug_level,0);  # or some integer

       is basically equivalent to this:
