The famous Fontimator (FKA 'Zipomator'), which automates everything for us. Developed for AlefAlefAlef and Fontimonim.
A full feature list and a blog post describing our use are soon to come.
This plugin is here on GitHub, to give inspiration and examples of what a font foundry can achieve. The license for this plugin is distributed under CC-NC-ND which does not allow commercial use and/or redistribution of the code (or parts of it). Sorry guys, we worked hard on this for over half a year.
Let us know if you have any uses you want to get an exclusion for.
