-- | Definition of a CSP core-language.
--   
--   This package contains an interface for the CSP core-language. It
--   defines processes, events, event sets, and a domain specific language
--   for process operations like parallel or interleaving processes.
@package CSPM-CoreLanguage
@version 0.3.1.0


-- | This module defines the event-related part of an interface between the
--   CSPM-CoreLanguage and the underlying implementation. The underlying
--   implementation has to instantiate the type families <a>Event</a>,
--   <a>EventSet</a>, <a>RenamingRelation</a> and the class <a>BE</a>
--   (<a>BE</a>== base event).
--   
--   For full CSPM support (channels with multiple fields, event closure
--   sets etc.) CSPM.CoreLanguage.Field is also needed.
module CSPM.CoreLanguage.Event

-- | Sigma is the set of all events that appear in a system.
type Sigma i = EventSet i

-- | The first argument of all functions in <a>BE</a> is a
--   phantom-type-argument, i.e. applications pass _|_ and implementations
--   must not use this value.

-- | This modules defines an FDR-compatible CSP core language. The core
--   language deals with CSP-related constructs like processes and events.
--   
--   The implementation of the underlying language must provide instances
--   for the type families <a>Prefix</a>, <a>ExtProcess</a> and class
--   <a>BL</a>.
