Description of issue

I'd like to use homebrew for delivering a set of scripts.
The scripts have common dependencies and configs, and I'd like to share these between the scripts.
I was thinking of creating config files and a common library for the scripts, both of which the other scripts could the source.
I guess one approach is that during installation time the install can get hold of the absolute install path, so if each script includes source /foo/bar/functions.sh or similar, during installation time the path can be replaced with the action install path of the dependency file?
What's would be the recommended way to achieve this?

Install the stuff everything else needs as a formula and then depend on that formula in the other formula.
