Name:           vectorscan
Version:        5.4.11
Release:        6%{?dist}
Summary:        A portable fork of hyperscan, used as a high performance pcre replacement
# note google test framework not part of shipped binary
# vectorscan is BSD-3-Clause but it utilizes boost, which is a C++ template
# library and ends up embedded in the binary. BSL is included here for
# completeness for this reason, but may not strictly be required as
# the source is contained in the boost-devel packages.

%description
A fork of Intel's Hyperscan, modified to run on more
platforms. Hyperscan is a high-performance multiple regex matching
library. It follows the regular expression syntax of the commonly-used
libpcre library, but is a standalone library with its own C API.

Hyperscan uses hybrid automata techniques to allow simultaneous
matching of large numbers (up to tens of thousands) of regular
expressions and for the matching of regular expressions across streams
of data.

Hyperscan is typically used in a DPI library stack.
