232 App::FatPacker - pack your dependencies onto your script file
236 $ fatpack trace myscript.pl
237 $ fatpack packlists-for `cat fatpacker.trace` >packlists
238 $ fatpack tree `cat packlists`
239 $ (fatpack file; cat myscript.pl) >myscript.packed.pl
241 See the documentation for the L<fatpack> script itself for more information.
243 The programmatic API for this code is not yet fully decided, hence the 0.9
244 release version. Expect that to be cleaned up for 1.0.
248 Your current best avenue is to come annoy annoy mst on #toolchain on
249 irc.perl.org. There should be a non-IRC means of support by 1.0.

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