The Ruby font installer library (RFIL) is another attempt on font installation for TeX fonts. It consists of a set of example programs and several libraries for doing font related tasks, such as read/write tfm, afm, vf and enc files, creating font metrics, doing calculations and alike. The software is all written in Ruby.
