+// This is a fuzzing harness for Harfbuzz. Since Harfbuzz's input is generally
+// expected to be controlled by a remote party it's a possible vector for
+// security issues.
+//
+// Fuzzing is a black-box testing scheme where the black-box (Harfbuzz's shaping
+// engine in this case) is fed random input to see if it will misbehave.
+// Misbehaviours can often be turned into security or crash issues.
+//
+// It's expected that one will generally run this under valgrind in order to get
+// better detection of problems.

+them from
+
+        http://people.freedesktop.org/~hausmann/harfbuzz-test-fonts-0.1.tar.bz2
+
+In addition you may need two fonts (Mangal and Tunga) from Microsoft Windows

+
+The test program looks for them in a fonts/ subdirectory.
