The Shader Specification by the Libretro organization is a generic configuration file specification.
* # are treated as comments. Rest of the line is ignored. * Format is: key = value. There can be as many spaces as you like in-between. * Value can be wrapped inside "" for multiword strings. (foo = "hai u") * #include includes a config file in-place. * Path is relative to where config file was loaded unless an absolute path is chosen. * Key/value pairs from an #include are read-only, and cannot be modified.
