Extension Language Kit
     
         (Elk) A {Scheme} {interpreter} by Oliver Laumann
         and Carsten Bormann
         of the {Technical University of
        Berlin}.  Elk was designed to be used as a general extension
        language.  New {types} and {primitive} procedures can easily
        be added.  It has {first-class environments}, {dynamic-wind},
        {fluid-let}, {macros}, {autoload}ing and a {dump}.  It
        provides interfaces to {Xlib}, {Xt} and various {widget} sets;
        {dynamic loading} of extensions and {object files}; almost all
        artificial limitations removed; {generational}/{incremental
        garbage collector}; {Unix} {system call} extensions; {Records}
        (structures) and {bit strings}.
     
        Version: 2.2 is mostly {R3RS} compatible and runs on {Unix},
        {Ultrix}, {VAX}, {Sun-3}, {Sun-4}, {68000}, {i386}, {MIPS}, {IBM
        PC RT}, {RS/6000}, {HP700}, {SGI}, {Sony}, {MS-DOS}
        ({gcc}+{DJGPP} or {go32}).
