=head1 NAME
Data::Phrasebook::Debug - Phrasebook debugging.
=head1 SYNOPSIS
use Data::Phrasebook;
my $q = Data::Phrasebook->new(
class => 'Plain',
loader => 'Text',
file => 'phrases.txt',
debug => 2,
);
my $r = Phrasebook->new( file => 'phrases.txt', debug => 3 );
$r->debug(4);
$r->store(3,"Start");
my @log = $r->retrieve(2);
$r->clear();
=head1 DESCRIPTION
This module enables debug logging for phrasebook classes. It simply stores
all interaction with the phrasebook, which can then be interrogated. Do not
call directly, but via the class object.
There is a single storage for all levels of the Data::Phrasebook heirarchy.
This then enables storage and retrieval to be performed by the user. There
are several different levels of debugging, detailed as follows:
1 - Errors
2 - Warnings
3 - Information
4 - Variable Debugging
The first three are simple strings that are recorded during the processing.
However, the latter is specifically for dumping the contents of significant
variables.
Through the use of the debug() method, the debugging can be switched on and
off at significant points. The clear() method will clear the current trail of
debugging information.
