230 App::FatPacker - pack your dependencies onto your script file
234 $ fatpack trace myscript.pl

239 See the documentation for the L<fatpack> script itself for more information.
241 The programmatic API for this code is not yet fully decided, hence the 0.9
242 release version. Expect that to be cleaned up for 1.0.
246 Your current best avenue is to come annoy annoy mst on #toolchain on
247 irc.perl.org. There should be a non-IRC means of support by 1.0.

255 None as yet, though I probably owe lots of people thanks for ideas. Yet
256 another doc nit to fix.
