=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; cat myscript.pl) >myscript.packed.pl
+ $ fatpack file myscript.pl >myscript.packed.pl
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 0.9
release version. Expect that to be cleaned up for 1.0.
