+** testll.c -- test suite for 64bit integer (longlong) operations
+**
+** Summary: testll [-d] | [-h]
+**
+** Where:
+** -d set debug mode on; displays individual test failures
+** -v verbose mode; displays progress in test, plus -d
+** -h gives usage message.
+**
+** Description:
+** lltest.c tests the functions defined in NSPR 2.0's prlong.h.
+**
+** Successive tests begin to depend on other LL functions working
+** correctly. So, ... Do not change the order of the tests as run
+** from main().
+**
+** Caveats:
+** Do not even begin to think that this is an exhaustive test!
+**
+** These tests try a little of everything, but not all boundary
+** conditions and limits are tested.
+** You want better coverage? ... Add it.
