+This file implements a brew resolver for Galaxy requirements. In order for Galaxy
+to pick up on recursively defined and versioned brew dependencies recipes should
+be installed using the experimental `brew-vinstall` external command.
+
+More information here:
+
+https://github.com/jmchilton/brew-tests
+https://github.com/Homebrew/homebrew-science/issues/1191
+
+This is still an experimental module and there will almost certainly be backward
+incompatible changes coming.
