Pod::Simple::Debug(3)  Perl Programmers	Reference Guide	 Pod::Simple::Debug(3)

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 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:

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