+afl (security-oriented fuzzer)
+
+American fuzzy lop is a security-oriented fuzzer that employs a
+novel type of compile-time instrumentation and genetic algorithms to
+automatically discover clean, interesting test cases that trigger new
+internal states in the targeted binary. This substantially improves the
+functional coverage for the fuzzed code. The compact synthesized corpora
+produced by the tool are also useful for seeding other, more labor-
+or resource-intensive testing regimes down the road.
+
+To use afl with binary-only code (no source available), a custom qemu
+wrapper is used. This does NOT require a system-wide installation of
+qemu, but it does require the source to qemu. To build qemu support,
+download the qemu source from:
+
+http://wiki.qemu-project.org/download/qemu-2.3.0.tar.bz2
+
+Save the file in the same directory as the afl.SlackBuild script.
+
+If binary-only support is not needed, don't download the qemu source. This
+will speed up the build quite a bit.

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.
