Vectorscan is a portable fork of Intel's Hyperscan, a high-performance multiple
regex matching library. It follows the regular expression syntax of the
commonly-used libpcre library, yet functions as a standalone library with its
own API written in C.

Vectorscan uses hybrid automata techniques to allow simultaneous matching of
large numbers (up to tens of thousands) of regular expressions, as well as
matching of regular expressions across streams of data.

This portable fork extends support beyond x86 to additional architectures
including ARM NEON/ASIMD and Power VSX, making it suitable for a wider range
of platforms while maintaining API compatibility with Hyperscan 5.4.
