I have probably mentioned this before, but don't really like they way
applications/tools are handled in Dub.
For example, I just added DStep[1] as a package. Looking at the
installation instructions on the package it says to add dstep to your
project's package.json. I don't know how much sense that makes for a
standalone tool that can be used without a project.
