NAME
    Net::XMPP::Debug - XMPP Debug Module

SYNOPSIS
    Net::XMPP::Debug is a module that provides a developer easy access to logging debug information.

DESCRIPTION
    Debug is a helper module for the Net::XMPP modules. It provides the Net::XMPP modules with an
    object to control where, how, and what is logged.

  Basic Functions
        $Debug = Net::XMPP::Debug->new();

        $Debug->Init(
               level  => 2,
               file   => "stdout",
               header =>"MyScript");

        $Debug->Log0("Connection established");

METHODS
  Basic Functions
    new
            new(hash)

        creates the Debug object. The hash argument is passed to the Init function. See that
        function description below for the valid settings.

    Init
            Init(
                 level      => integer,
                 file       => string,
                 header     => string,
                 setdefault => 0|1,
                 usedefault => 0|1,
                 time       => 0|1)

        initializes the debug object.

        The level determines the maximum level of debug messages to log:

          0 - Base level Output (default)
          1 - High level API calls
          2 - Low level API calls
          ...
          N - Whatever you want....

        The file determines where the debug log goes. You can either specify a path to a file, or
        "stdout" (the default). "stdout" tells Debug to send all of the debug info sent to this
        object to go to stdout.

        header is a string that will preappended to the beginning of all log entries. This makes it
        easier to see what generated the log entry (default is "Debug").

        setdefault saves the current filehandle and makes it available for other Debug objects to
        use. To use the default set usedefault to 1.

        The time parameter specifies whether or not to add a timestamp to the beginning of each
        logged line.

    LogN
          LogN(array)

        Logs the elements of the array at the corresponding debug level N. If you pass in a
        reference to an array or hash then they are printed in a readable way. (ie... Log0, Log2,
        Log100, etc...)

EXAMPLE
      $Debug = Net::XMPP:Debug->new(level=>2,
                                   header=>"Example");

      $Debug->Log0("test");

      $Debug->Log2("level 2 test");

      $hash{a} = "atest";
      $hash{b} = "btest";

      $Debug->Log1("hashtest", \%hash);

    You would get the following log:

        Example: test
        Example: level 2 test
        Example: hashtest { a=>"atest" b=>"btest" }

    If you had set the level to 1 instead of 2 you would get:

        Example: test
        Example: hashtest { a=>"atest" b=>"btest" }
