.SH NAME
PAR::Filter::Bytecode \- Bytecode filter
.SH SYNOPSIS
.IX Header "SYNOPSIS"
.Vb 1
\&    PAR::Filter::Bytecode\->apply(\e$code); # transforms $code
.Ve
.SH DESCRIPTION
.IX Header "DESCRIPTION"
\&\fBThis 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.\fR
.PP
This filter uses B::Bytecode to turn the script into comment-free,
architecture-specific Perl bytecode, and uses ByteLoader to load
back on execution.
.PP
For pp users, please add an extra \fB\-M\fR option, like this:
.PP
.Vb 1
\&    pp \-f Bytecode \-M ByteLoader
.Ve
.PP
Otherwise, the implicit dependency on ByteLoader will not be detected.
.SH CAVEATS
.IX Header "CAVEATS"
This backend exhibits all bugs listed in B::Bytecode, and then some.
.PP
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).
.PP
Bytecode is not supported by perl 5.9 and later.
.SH "SEE ALSO"
.IX Header "SEE ALSO"
