+  Descritpion: 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 appropropriate.
