Tom's Obvious, Minimal Language is a file format for configuration files. It is designed to be easy to read and write by being minimal and by using human-readable syntax. The project standardizes the implementation of the ubiquitous INI file format, removing ambiguity from its interpretation. Originally created by Tom Preston-Werner, the TOML specification is open source. TOML is used in a number of software projects and has libraries implemented in all popular programming languages.
