Moscow ML
     
        A light-weight implementation of {Standard ML} written by
        Sergei Romanenko  of the
        {Keldysh Institute of Applied Mathematics} with assistance
        from Peter Sestoft , {Royal Veterinary
        and Agricultural University}.  Moscow ML is based on {CAML
        Light}.
     
        Version: 1.20 implements the Standard ML Core language.
     
        The sublanguage of Modules implemented by Moscow ML contains
        signatures and non-nested structures, and identifies
        structures with source files.  It is certainly less expressive
        than the full Standard ML Modules language, but the
        {type-safe} {separate compilation} facility is simple, useful,
        and easy to use.  It is the intention to implement the full
        Standard ML Modules language (including functors) in due
        course.
     
        Compilation of a {signature} produces a compiled interface
        file, which is used when compiling other signatures and
        structures.
     
        Compilation of a structure produces a {bytecode} file.
        Bytecode files are compact and load fast.  For instance, a
        3250-line program consisting of 24 structures and 17
        signatures compiles to 221 KB of bytecode and 241 KB of
        compiled signatures.  Starting the ML system and loading the
        24 bytecode files takes 1-2 cpu seconds plus network delays,
        less that 5 seconds real time in all.
     
        Release 1.20 permits loading of precompiled bytecode files
        into the top-level interactive session.  The next release will
        be able to create stand-alone executables by linking bytecode
        files.
     
        There is a mechanism for adding basis libraries, as in {Caml
        Light}.  Release 1.20 includes the basis libraries Array,
        List, and Vector and the {MS-DOS} version includes the
        Graphics library from {Caml Light}.
     
        In principle, Moscow ML can be compiled on any {platform}
        supported by {Caml Light}.  So far we have tried {Intel
        80386}-based {IBM PC}s running {MS-DOS}, {Microsoft Windows},
        {OS/2} or {Linux}, {DEC MIPS} running {Ultrix}, {DEC Alpha}
        running {OSF/1}, {Sun-4} running {SunOS}, {HP9000} running
        {HP/UX}, {SGI MIPS} running {IRIX} 5.
     
        Moscow ML is particularly useful when fast compilation and
        modest storage consumption are more important than fast
        program execution.
     
        Thanks to the efficient Caml Light run-time system used in
        Moscow ML, it compiles fast and uses little memory, typically
        5-10 times less memory than {SML/NJ} 0.93 and 2-3 times less
        than {Edinburgh ML}.  Yet the bytecode is only 3 to 10 times
        slower than SML/NJ 0.93 compiled native code (fast on {IBM
        PC}s, slower on {RISC}s).

        {Caml Light} 0.61 and {gcc} are required to recompile Moscow
        ML for {Unix} or Caml Light 0.61, {djgpp}, {Perl}, and
        {Borland C++} version 2.0 (or later) to recompile Moscow ML
        for {DOS}.
