PCRE
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.
Release 10 of PCRE2 is 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.
