ContextL

ContextL is a CLOS extension that supports Context-oriented Programming (COP), note that this is a slightly misleading term.

ContexL itself is very portable and makes no system specific requirements, however it is dependent on the Closer to MOP compatibility layer which only supports a subset of available LISP/CLOS implementations which in practice means that on OS/2 ContexL currently only runs on CLISP although that may change in the near future.
