=head1 NAME

App::FatPacker - pack your dependencies onto your script file

=head1 SYNOPSIS

$ fatpack pack myscript.pl >myscript.packed.pl

Or, with more step-by-step control:

$ fatpack trace myscript.pl
  $ fatpack packlists-for `cat fatpacker.trace` >packlists
  $ fatpack tree `cat packlists`
  $ fatpack file myscript.pl >myscript.packed.pl

Each command is designed to be simple and self-contained so that you can modify
the input/output of each step as needed. See the documentation for the
L<fatpack> script itself for more information.

The programmatic API for this code is not yet fully decided, hence the 0.x
release version. Expect that to be cleaned up for 1.0.

=head1 CAVEATS

As dependency module code is copied into the resulting file as text, only
pure-perl dependencies can be packed, not compiled XS code.

The currently-installed dependencies to pack are found via F<.packlist> files,
which are generally only included in non-core distributions that were installed
by a CPAN installer. This is a feature; see L<fatpack/packlists-for> for
details. (a notable exception to this is FreeBSD, which, since its packaging
system is designed to work equivalently to a source install, does preserve
the packlist files)

=head1 SEE ALSO

L<article for Perl Advent 2012|http://www.perladvent.org/2012/2012-12-14.html>

L<pp> - PAR Packager, a much more complex architecture-dependent packer that
can pack compiled code and even a Perl interpreter

=head1 SUPPORT

Bugs may be submitted through L<the RT bug tracker|https://rt.cpan.org/Public/Dist/Display.html?Name=App-FatPacker>
(or L<bug-App-FatPacker@rt.cpan.org|mailto:bug-App-FatPacker@rt.cpan.org>).

You can normally also obtain assistance on irc, in #toolchain on irc.perl.org.
