   Populating the "scripts" section of the package.json def has some niceties. Mainly:

   • no need to know about scripty to be able to tell what a script does
   • you can easily check what all the scripts do via npm run.

   I had thought about making a tool that populated the "scripts" section, but never got to a point where I really needed it – I guess I've only used the "scripts" field with simple configs.

   I'll try using scripty and report back in case I ever feel the need for this populater feature. :)
