+=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
+
+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 SEE ALSO
+
+L<article for Perl Advent 2012|http://www.perladvent.org/2012/2012-12-14.html>
+
+=head1 SUPPORT
+
+Your current best avenue is to come annoy mst on #toolchain on
+irc.perl.org. There should be a non-IRC means of support by 1.0.
