README.txt 

DESCRIPTION

  plinko is a simple lisp interpreter that takes advantage of advanced
  operating system features irrespective of their practicality such as
  using the nsa instruction popcount for mark sweep garbage collection
  overcommit memory, segment registers, and other dirty hacks that the
  popular interpreters cannot do; this lets plinko gain a considerable
  performance edge while retaining an event greater edge in simplicity

  We hope you find these sources informative, eductional, and possibly
  useful too. Lisp source code, written in its dialect is included too
  under //tool/plinko/lib and unit tests which clarify their usage can
  be found in //test/tool/plinko.
