+** 1996 - Netscape Communications Corporation

+**
+** Name: depend.c
+** Description: Test to enumerate the dependencies
+*
+** Modification History:
+** 14-May-97 AGarcia- Converted the test to accomodate the debug_mode flag.
+** The debug mode will print all of the printfs associated with this test.
+** The regress mode will be the default mode. Since the regress tool limits
+** the output to a one line status:PASS or FAIL,all of the printf statements
+** have been handled with an if (debug_mode) statement.
