    // produce source code for all versions from the main version.
    // Do note that the preprocessor can only convert between two projects when they are either on the same Minecraft
    // version (but use different mappings, e.g. 1.16.2 forge to fabric), or when they are using the same intermediary
    // mappings (but on different Minecraft versions, e.g. 1.12.2 forge to 1.8.9 forge, or 1.16.2 fabric to 1.18 fabric)
    // but not both at the same time, i.e. you cannot go straight from 1.12.2 forge to 1.16.2 fabric, you need to go via
    // an intermediary 1.16.2 forge project which has something in common with both.
    // For any link, you can optionally specify a file containing extra mappings which the preprocessor cannot infer by
    // itself, e.g. forge intermediary names do not contain class names, so you may need to supply mappings for those
    // manually.
