yerk
     
         after yerkes observatory an object-oriented
        language based on a forth kernel with some major
        modifications.  it was originally known as neon, developed
        and sold as a product by kriya systems from 1985 to 1989.
        several people at the university of chicago have maintained
        yerk since its demise as a product.  because of possible
        trademark conflict they named it yerk, which is not an acronym
        for anything, but rather stands for yerkes observatory, part
        of the department of astronomy and astrophysics at u of c.
