New Perl Compatible Regular Expression Library - development files

 This is PCRE2, the new implementation of PCRE, a library of functions
 to support regular expressions whose syntax and semantics are as
 close as possible to those of the Perl 5 language. New projects
 should use this library in preference to the older library,
 confusingly called pcre3 in Debian.
 .
 Unlike the previous version of PCRE, there is no C++ library included
 with PCRE2. Users who wish to avoid porting their C++ code to use the
 PCRE2 C API might want to consider the libre2-dev package in Debian
 which attempts to provide a similar C++ API to that provided by
 libpcrecpp in previous versions of PCRE.
 .
 This package contains the development files, including headers,
 static libraries, and documentation.
