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

SSYYNNOOPPSSIISS #

  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;

DDEESSCCRRIIPPTTIIOONN #

 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 _b_e_f_o_r_e 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, _s_o_m_e_n_u_m)" 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 (\$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 ();
