Introduction
CHSM is a language system for specifying
concurrent, hierarchical, finite state machines
(a realization of "statecharts")
to model and control reactive systems.
CHSM uses its own specification langauge
annotated with C++ code fragments
in the tradition of yacc with C code fragments.
CHSM has been used successfullly in production environments such as
CERN
and
Philips.
Here is an independent review from users at CERN.

Fully Documented
Unix-style "man" pages are included
describing the specification language, C++ classes, and compiler.
There are also a few included examples.
The source code is also generously commented.
Although the current implementation
has evolved over time,
the
original description
is available.
