     "QEMU is a generic machine emulator and virtualizer.  This package
of QEMU is used only by the american fuzzy lop package.

When used as a machine emulator, QEMU can run OSes and programs made for one
machine (e.g. an ARM board) on a different machine---e.g., your own PC.  By
using dynamic translation, it achieves very good performance.

When used as a virtualizer, QEMU achieves near native performances by
executing the guest code directly on the host CPU.  QEMU supports
virtualization when executing under the Xen hypervisor or using
the KVM kernel module in Linux.  When using KVM, QEMU can virtualize x86,
server and embedded PowerPC, and S390 guests.")

     "AFLplusplus 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.
It is a fork of American Fuzzy Lop fuzzer and features:
@itemize
@item A more recent qemu version.
@item More algorithms like collision-free coverage, enhanced laf-intel &
redqueen, AFLfast++ power schedules, MOpt mutators, unicorn_mode, etc.

keyboard interface is modeled after vim, so vim users should feel at home
