NAME
       Log::Message::Simple - Simplified interface to Log::Message

SYNOPSIS
           use Log::Message::Simple qw[msg error debug
                                       carp croak cluck confess];

           use Log::Message::Simple qw[:STD :CARP];

           ### standard reporting functionality
           msg(    "Connecting to database",           $verbose );
           error(  "Database connection failed: $@",   $verbose );
           debug(  "Connection arguments were: $args", $debug );

           ### standard carp functionality
           carp(   "Wrong arguments passed: @_" );
           croak(  "Fatal: wrong arguments passed: @_" );
           cluck(  "Wrong arguments passed -- including stacktrace: @_" );
           confess("Fatal: wrong arguments passed -- including stacktrace: @_" );

           ### retrieve individual message
           my @stack = Log::Message::Simple->stack;
           my @stack = Log::Message::Simple->flush;

           ### retrieve the entire stack in printable form
           my $msgs  = Log::Message::Simple->stack_as_string;
           my $trace = Log::Message::Simple->stack_as_string(1);

           ### redirect output
           local $Log::Message::Simple::MSG_FH     = \*STDERR;
           local $Log::Message::Simple::ERROR_FH   = \*STDERR;
           local $Log::Message::Simple::DEBUG_FH   = \*STDERR;

           ### force a stacktrace on error
           local $Log::Message::Simple::STACKTRACE_ON_ERROR = 1

DESCRIPTION
       This module provides standardized logging facilities using the "Log::Message" module.

FUNCTIONS
   msg("message string" [,VERBOSE])
       Records a message on the stack, and prints it to "STDOUT" (or actually $MSG_FH, see the
       "GLOBAL VARIABLES" section below), if the "VERBOSE" option is true.  The "VERBOSE" option
       defaults to false.

       Exported by default, or using the ":STD" tag.

   debug("message string" [,VERBOSE])
       Records a debug message on the stack, and prints it to "STDOUT" (or actually $DEBUG_FH,
       see the "GLOBAL VARIABLES" section below), if the "VERBOSE" option is true.  The "VERBOSE"
       option defaults to false.

       Exported by default, or using the ":STD" tag.

   error("error string" [,VERBOSE])
       Records an error on the stack, and prints it to "STDERR" (or actually $ERROR_FH, see the
       "GLOBAL VARIABLES" sections below), if the "VERBOSE" option is true.  The "VERBOSE"
       options defaults to true.

       Exported by default, or using the ":STD" tag.

   carp();
       Provides functionality equal to "Carp::carp()" while still logging to the stack.

       Exported by using the ":CARP" tag.

   croak();
       Provides functionality equal to "Carp::croak()" while still logging to the stack.

       Exported by using the ":CARP" tag.

   confess();
       Provides functionality equal to "Carp::confess()" while still logging to the stack.

       Exported by using the ":CARP" tag.

   cluck();
       Provides functionality equal to "Carp::cluck()" while still logging to the stack.

       Exported by using the ":CARP" tag.

CLASS METHODS
   Log::Message::Simple->stack()
       Retrieves all the items on the stack. Since "Log::Message::Simple" is implemented using
       "Log::Message", consult its manpage for the function "retrieve" to see what is returned
       and how to use the items.

   Log::Message::Simple->stack_as_string([TRACE])
       Returns the whole stack as a printable string. If the "TRACE" option is true all items are
       returned with "Carp::longmess" output, rather than just the message.  "TRACE" defaults to
       false.

   Log::Message::Simple->flush()
       Removes all the items from the stack and returns them. Since "Log::Message::Simple" is
       implemented using "Log::Message", consult its manpage for the function "retrieve" to see
       what is returned and how to use the items.

GLOBAL VARIABLES
       $ERROR_FH
           This is the filehandle all the messages sent to "error()" are being printed. This
           defaults to *STDERR.

       $MSG_FH
           This is the filehandle all the messages sent to "msg()" are being printed. This
           default to *STDOUT.

       $DEBUG_FH
           This is the filehandle all the messages sent to "debug()" are being printed. This
           default to *STDOUT.

       $STACKTRACE_ON_ERROR
           If this option is set to "true", every call to "error()" will generate a stacktrace
           using "Carp::shortmess()".  Defaults to "false"
