PCRE2 License

=============

|
| SPDX-License-Identifier: | BSD-3-Clause WITH PCRE2-exception |
|
|
|---------|-------|
|
|
|
|
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.
