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.

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

few random help scripts I'm using while I play with sage2 on my raspberry pi.

This is meant to go with my sage-cookbook and my own pis.

Capturing here incase others wander into this stuff and want to try it out.

To test this all out and just putter around with sage on my pi from my desktop I'm doing the following:

• Launchinging tmux session with sage2 server using sage2tmux.sh
• Launching a fullscreen iceweasle on the pi as pi using weblauncher.sh
