+ * HISTORY
+ * 
+ * 22-Nov-2004	M K Ravishankar (rkm@cs.cmu.edu) at Carnegie Mellon University
+ * 		Imported from s3.2, for supporting s3 format continuous
+ * 		acoustic models.
+ * 
+ * 10-Mar-1999	M K Ravishankar (rkm@cs.cmu.edu) at Carnegie Mellon University.
+ * 		Added vector_accum(), vector_vqlabel(), and vector_vqgen().
+ * 
+ * 09-Mar-1999	M K Ravishankar (rkm@cs.cmu.edu) at Carnegie Mellon University.
+ * 		Added vector_is_zero(), vector_cmp(), and vector_dist_eucl().
+ * 		Changed the name vector_dist_eval to vector_dist_maha.
+ * 
+ * 07-Oct-98	M K Ravishankar (rkm@cs.cmu.edu) at Carnegie Mellon University.
+ * 		Added distance computation related functions.
