description         Whole-program optimizing compiler for the SML
long_description    MLton is a whole-program optimizing compiler for the Standard ML programming language. \
                    MLton generates small executables with excellent runtime performance, utilizing untagged and unboxed native integers, \
                    reals, and words, unboxed native arrays, fast arbitrary-precision arithmetic based on GMP, and multiple code generation \
                    and garbage collection strategies. In addition, MLton provides a feature rich Standard ML programming environment, \
                    with full support for SML97 as given in The Definition of Standard ML (Revised), a number of useful language extensions, \
                    a complete implementation of the Standard ML Basis Library, various useful libraries, a simple and fast C foreign function interface, \
                    the ML Basis system for programming with source libraries, and tools such as a lexer generator, a parser generator and a profiler.
