Module type OCamlResRegistry.FormatSource

The type of format plug-ins. Differs from OCamlResFormats.Format since it is dedicated to be used by the command line tool. For this, the parameters are provided not as a data type but as a list of command line args that can mutate global references, which can then be read from the output function. This is because parameters come from the user, not the programmer. Also, the tool is dedicated to use with the filesystem, so the type of data is fixed to strings representing the raw encoding of data.
