# PCRE2

The PCRE library is a set of functions that implement regular expression pattern matching using the same syntax and semantics as Perl 5.

Optionally used in Qt Core (QRegularExpression). Configure with -system-pcre or -no-pcre to avoid.

The sources can be found in work/qtbase-everywhere-src-5.11.3/src/3rdparty/pcre2.

      PCRE2 LICENCE
      -------------

      PCRE2 is a library of functions to support regular expressions whose syntax
      and semantics are as close as possible to those of the Perl 5 language.

      Releases 10.00 and above of PCRE2 are distributed under the terms of the "BSD"
      licence, as specified below, with one exemption for certain binary
      redistributions. The documentation for PCRE2, supplied in the "doc" directory,
      is distributed under the same terms as the software itself. The data in the
      testdata directory is not copyrighted and is in the public domain.

      The basic library functions are written in C and are freestanding. Also
      included in the distribution is a just-in-time compiler that can be used to
      optimize pattern matching. This is an optional feature that can be omitted when
      the library is built.

      EXEMPTION FOR BINARY LIBRARY-LIKE PACKAGES
      ------------------------------------------

      The second condition in the BSD licence (covering binary redistributions) does
      not apply all the way down a chain of software. If binary package A includes
      PCRE2, it must respect the condition, but if package B is software that
      includes package A, the condition is not imposed on package B unless it uses
      PCRE2 independently.
