Simple build system for packages

Uses bash scripts for the plans - check out github.com/habitat-sh/core-plans

When making habitat packages you are building packages in isolation, so they don't depend on the build system's libraries tools, and you can make them portable. They are kind of making their own OS packages available.

Any of these packages can run on any linux OS that has a modern kernel on a x86_64 architecture (no love for RPi). Lots of tutorials.

hab studio enter

• what you will see is only what was in the directory that you entered - it will look for a .bah
