- * The <i>Group Mutual Exclusion Object</i> is used to describe mutual exclusion
- * relationships between groups of streams. This object is organized in terms of
- * records, each containing one or more streams, where a stream in record N
- * cannot coexist with a stream in record M for N != M (however, streams in the
- * same record can coexist). This mutual exclusion object would be used
- * typically for the purpose of language mutual exclusion, and a record would
- * consist of all streams for a particular language.
