- * set.h -- definitions for packed arrays of bits
- *
- * This header file describes the data structures which comprise a
- * facility for efficiently implementing packed arrays of bits
- * (otherwise known as sets, cf. Pascal).
- *
- * A set is a vector of bits and is implemented here as an array of
- * unsigned integers. The low order bits of set[0] give the index of
- * the last word of set data. The higher order bits of set[0] are
- * used to store data associated with the set. The set data is
- * contained in elements set[1] ... set[LOOP(set)] as a packed bit
- * array.
- *
- * A family of sets is a two-dimensional matrix of bits and is
- * implemented with the data type "set_family".
- *
- * BPI == 32 and BPI == 16 have been tested and work.
