+/***********************************************************************
+**  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.
