         perl -MTest::Valgrind leaky.pl
 
+    Due to the nature of perl's memory allocator, this module can't track
+    leaks of Perl objects. This includes non-mortalized scalars and memory
+    cycles. However, it can track leaks of chunks of memory allocated in XS
+    extensions with "Newx" and friends or "malloc". As such, it's
+    complementary to the other very good leak detectors listed in the "SEE
+    ALSO" section.
+
 CONFIGURATION
     You can pass parameters to "import" as a list of key / value pairs,
     where valid keys are :
 
-    "supp => $file"
+    *   "supp => $file"
+
         Also use suppressions from $file besides perl's.
 
-    "no_supp => $bool"
+    *   "no_supp => $bool"
+
         If true, do not use any suppressions.
 
-    "callers => $number"
+    *   "callers => $number"
+
         Specify the maximum stack depth studied when valgrind encounters an
-        error. Raising this number improves granularity. Default is 50.
+        error. Raising this number improves granularity. Default is 12.
+
+    *   "extra => [ @args ]"
 
-    "extra => [ @args ]"
         Add @args to valgrind parameters.
 
-    "diag => $bool"
+    *   "diag => $bool"
+
         If true, print the raw output of valgrind as diagnostics (may be
         quite verbose).
 
-    "no_test => $bool"
+    *   "no_test => $bool"
+
         If true, do not actually output the plan and the tests results.
 
+    *   "cb => sub { my ($val, $name) = @_; ...; return $passed }"
+
+        Specifies a subroutine to execute for each test instead of
+        "Test::More::is". It receives the number of bytes leaked in $_[0]
+        and the test name in $_[1], and is expected to return true if the
+        test passed and false otherwise. Defaults to
+
+            sub {
+             is($_[0], 0, $_[1]);
+             (defined $_[0] and $_[0] == 0) : 1 : 0
+            }

 CAVEATS
     You can't use this module to test code given by the "-e" command-line
     switch.
