+=head1 NAME
+
+App::FatPacker - pack your dependencies onto your script file
+
+=head1 SYNOPSIS
+
+ $ fatpack trace myscript.pl
+ $ fatpack packlists-for `cat fatpacker.trace` >packlists
+ $ fatpack tree `cat packlists`
+ $ (fatpack file; cat 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.
+
+=head1 SUPPORT
+
+Your current best avenue is to come annoy annoy mst on #toolchain on
+irc.perl.org. There should be a non-IRC means of support by 1.0.
+
+=head1 AUTHOR
+
+Matt S. Trout (mst) <mst@shadowcat.co.uk>
+
+=head2 CONTRIBUTORS
+
+None as yet, though I probably owe lots of people thanks for ideas. Yet
+another doc nit to fix.
