Do you like the simplicity of INI files but wish they were formally specified and had a few more features? So did Tom Preston-Werner, founder of services such as GitHub and Gravatar. He created Tom's Obvious, Minimal Language, or TOML for short. This relatively new format is seeing increasing adoption in new projects. In fact, you have used it multiple times by now as well: Cargo's dependencies are specified in every project's Cargo.toml file!
