How do I install these formulae?

brew install mighty-gerbils/gerbil/<formula>

Or brew tap mighty-gerbils/gerbil and then brew install <formula>.

Build the HEAD of Master

Sometimes, like for testing pre-release, we want to build and test the lastest commit to the master branch.

brew install mighty-gerbils/gerbil/gerbil-scheme

Documentation

`brew help`, `man brew` or check [Homebrew's documentation](https://docs.brew.sh).

Packages: gerbil-scheme, gerbil-scheme-gcc and gerbil-scheme-clang

These packages are literate and tangled from this README.org.

HACKING

Trying to make it work for the github thing often means fixing a of whitespace and other styles that are frowned upon.

brew style --fix  mighty-gerbils/gerbil/gerbil-scheme

brew audit mighty-gerbils/gerbil/gerbil-scheme --online --new
