+
+ In the current version, the parameter KAPPA in the Kahan's test
+ for orthogonality is set to 0.717, the same as used by Gragg & Reichel.
+ However computational experience indicates that this is a little too 
+ strict and will frequently force reorthogonalization when it is not
+ necessary to do so. 
+
+ Also the "moving boundary" idea is not currently activated in the nonsymmetric
+ code since it is not conclusive that it's the right thing to do all the time.  
+ Requires further investigation.
+
+ As of 02/01/93 Richard Lehoucq assumes software control of the codes from
+ Phuong Vu. On 03/01/93 all the *.F files were migrated SCCS. The 1.1 version
+ of codes are those received from Phuong Vu. The frozen version of 07/08/92
+ is now considered version 1.1.
+
+ Version 2.1 contains two new symmetric routines, sesrt and seupd. 
+ Changes as well as bug fixes for version 1.1 codes that were only corrected 
+ for programming bugs are version 1.2. These 1.2 versions will also be in version 2.1.
+ Subroutine [d,s]saupd now requires slightly more workspace. See [d,s]saupd for the
+ details.
