1 Introduction
The purpose of this document is to provide a short introduction to PLAN and
the basic usage of the 3.2 OCaml implementation. It will be of help to
people just starting with PLAN, although experienced PLAN programmers might
use this as a quick reference.
PLAN 3.2 is implemented in OCaml version 2.02. Previous versions of PLAN
(up to 2.22) were written in Java [2] (and an extension,
Pizza [6]), which has its own documentation. This
document assumes that installation (of both PLAN and its required
components) has completed successfully; refer to the Installation document
for that.
