NAME

       PAR::Filter - Input filter for PAR

SYNOPSIS

	   $code = 'use strict; print "Hello, World!
";';
	   $ref = PAR::Filter->new('PodStrip', 'Bleach')->apply($code);
	   print $code;    # pod-stripped and obfuscated code
	   print $$ref;    # same thing

	   $ref = PAR::Filter->new('PodStrip', 'Bleach')->apply('file.pl');
	   print $$ref;    # same thing, applied to file.pl

DESCRIPTION

       Starting with PAR 0.76, "pp -f" takes a filter name, like "Bleach", and invokes this module to transform the programs with
       PAR::Filter::Bleach.  Similarily, "pp -F Bleach" applies the Bleach filter to all included modules.

       It is possible to pass in multiple such filters, which are applied in turn.

       The output of each such filter is expected be semantically equivalent to the input, although possibly obfuscated.

       The default list of filters include:

       o   PAR::Filter::Bleach

	   The archetypical obfuscating filter.

       o   PAR::Filter::Obfuscate

	   Use B::Deobfuscate to strip away indents and comments, as well as mangling variable names.

       o   PAR::Filter::PatchContent

	   Fix PAR-incompatible modules, applied to modules by default.

       o   PAR::Filter::PodStrip

	   Strip away POD sections, applied to modules by default.

       o   PAR::Filter::Bytecode

	   Use B::Bytecode to strip away indents and comments.	This filter is deprecated! For source hiding, have a look at PAR::Filter::Crypto
	   instead and make sure to read about its caveats.

NAME

       PAR::Filter::Bytecode - Bytecode filter

SYNOPSIS

	   PAR::Filter::Bytecode->apply($code); # transforms $code

DESCRIPTION

       This filter is deprecated. The B::Bytecode code has been removed from the newest development series of perl and will not be included in
       perl 5.10 any more. Please have a look at Steve Hay's PAR::Filter::Crypto module if you want to hide your sources.

       This filter uses B::Bytecode to turn the script into comment-free, architecture-specific Perl bytecode, and uses ByteLoader to load back on
       execution.

       For pp users, please add an extra -M option, like this:

	   pp -f Bytecode -M ByteLoader

       Otherwise, the implicit dependency on ByteLoader will not be detected.

CAVEATS

       This backend exhibits all bugs listed in B::Bytecode, and then some.

       Bytecode support is considered to be extremely fragile on Perl versions earlier than 5.8.1, and is still far from robust (as of this
       writing).

       Bytecode is not supported by perl 5.9 and later.
