-  Title:       SETENV.H
-  Description: Logic in most setenv.sh files can create the following problem
-               on many platforms:
-
-                 $ . ./setenv.sh
-                 basename: invalid option -- 'b'
-                 Try `basename --help' for more information.
-
-               The problem is that $0 is the current running shell which may include
-               a dash in front:
-
-                 $ echo $0
-                 -bash
-
-               But often is just /bin/bash (and the problem does not occur.  The fix
-               is:
-
-                 -if [ "$(basename $0)" = "setenv.sh" ]; then
-                 +if [ "$_" = "$0" ] ; then
-  Status:      Open
-  Priority:    Low.  Use of setenv.sh is optional and most platforms do not have
-               this problem.  Scripts will be fixed one-at-a-time as is appropriate.
