description="
Perl-compatible regular expressions (version 2).

The PCRE2 library is a set of C functions that implement regular
expression pattern matching using the same syntax and semantics as
Perl 5.  PCRE2 has its own native API, as well as a set of wrapper
functions that correspond to the POSIX regular expression API.
The PCRE2 library is free, even for building proprietary software.
It comes in three forms, for processing 8-bit, 16-bit, or 32-bit code
units, in either literal or UTF encoding.
