What is a FIMPP file?
Source code file written in FiM++, an esoteric programming language based on the My Little Pony cartoon series; uses the form of a written letter to define classes (e.g., Dear Princess Celestia: Letter One followed by other statements); similar to other humorous programming languages such as LOLCODE (.LOL files).
