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...

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

        $debuglevel = 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.

CCAAVVEEAATTSS
       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.

GGUUTTSS
       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 (\$debuglevel,0);  # or some integer

       is basically equivalent to this:

         my $debuglevel;
         BEGIN { $debuglevel = 0 }
         BEGIN { sub Pod::Simple::DEBUG () { $debuglevel }
         use Pod::Simple ();
