The readme has more explanation: > Wuffs (Wrangling Untrusted File Formats Safely) is formerly known as Puffs (Parsing Untrusted File Formats Safely). > Wuffs is a memory-safe programming language (and a standard library written in that language) for wrangling untrusted file formats safely. Wrangling includes parsing, decoding and encoding. Example file formats include images, audio, video, fonts and compressed archives. > Wuffs is not a general purpose programming language. It is for writing libraries, not programs. The idea isn't to write your whole program in Wuffs, only the parts that are both performance-conscious and security-conscious. For example, while technically possible, it is unlikely that a Wuffs compiler would be worth writing entirely in Wuffs.
