These formulae provide software related to the INDI telescope automation tools. This is forked in a round-about way from polakovic's repo (https://github.com/polakovic/homebrew-astronomy).
Just brew tap indilib/indi and then brew install <formula>.
If the formula conflicts with one from mxcl/master or another tap, you can brew install indilib/indi/<formula>.
You can also install via URL:
brew install https://raw.github.com/indilib/homebrew-indi/master/<formula>.rbt
