+The check for solaris 'print' causes significant problems on a linux machine
+with dash as /bin/sh since it triggers the execution of "print" which on some 
+linux systems is a perl script which is part of mailcap. Worse, this perl 
+script calls "which file" and if successful ignores the path file was found 
+in and just runs "file" without a path. Each exection causes PATH to be searched.
+
+Simply assuming the shell's printf function works cuts out all the fork overhead
+and when parallel tasks are running, this overhead appears to be significant.
