Compiler-compilers are metaprograms for compiling compilers in their totality, complete with precompilers, lexical analyzers, parsers, and code generators. As such, compiler-compilers are considered kits, along with other tools and environments for generating full compilers.
Submissions should not include compilers for specific languages, which must be submitted elsewhere to proper subcategories for the source languages involved. Systems for generating separate compiler components (lexers/parsers, code generators or transformation tools) or cross-compilers must be submitted to their respective subcategories under /Compilers.
