Brainfuck

   <language> An eight-instruction programming language created
   by Urban Müller.  His goal was apparently to create a
   {Turing-complete} language with the smallest {compiler} ever,
   for the {Amiga OS} 2.0.  He eventually reduced his compiler to
   under 200 bytes.

   A Brainfuck program has a pointer that moves within an array
   of 30000 bytes, initially all set to zero.  The pointer
   initially points to the beginning of this array.  The language
   has eight commands, each of which is represented as a single
   character, and which can be expressed in terms of {C} as
   follows:

    >   ==>    ++p;
    <   ==>    --p;
    +   ==>    ++*p;
    -   ==>    --*p;
    .   ==>    putchar(*p);
    ,   ==>    *p = getchar();
    [   ==>    while (*p) {
    ]   ==>    }
