Glad you asked.  Turns out `appassembler` is a temporary stop on the way to this `binary-assembly` directory.  The difference is that the binary assembly has been `chmod`'ed properly.  You'll also find `.zip` and `.tar.gz` binary assemblies.  If we want to distribute our project, we'd do so by giving our those zipped assemblies.

In other words, you should be running from this directory, _not_ from appassembler.
