# This package currently links with lzma but does not require it.

%description
Honggfuzz is a general-purpose fuzzing tool. Given an input corpus
files, honggfuzz modifies input to a test program and utilize the
ptrace() API/POSIX signal interface to detect and log crashes. It
can also use software or hardware-based code coverage techniques
to produce more and more interesting inputs.
