| 1 | +PCRE2 LICENCE |
| 2 | +------------- |
| 3 | + |
| 4 | +PCRE2 is a library of functions to support regular expressions whose syntax |
| 5 | +and semantics are as close as possible to those of the Perl 5 language. |
| 6 | + |
| 7 | +Releases 10.00 and above of PCRE2 are distributed under the terms of the "BSD" |
| 8 | +licence, as specified below, with one exemption for certain binary |
| 9 | +redistributions. The documentation for PCRE2, supplied in the "doc" directory, |
| 10 | +is distributed under the same terms as the software itself. The data in the |
| 11 | +testdata directory is not copyrighted and is in the public domain. |
| 12 | + |
| 13 | +The basic library functions are written in C and are freestanding. Also |
| 14 | +included in the distribution is a just-in-time compiler that can be used to |
| 15 | +optimize pattern matching. This is an optional feature that can be omitted when |
| 16 | +the library is built. |

| 85 | +EXEMPTION FOR BINARY LIBRARY-LIKE PACKAGES |
| 86 | +------------------------------------------ |
| 87 | + |
| 88 | +The second condition in the BSD licence (covering binary redistributions) does |
| 89 | +not apply all the way down a chain of software. If binary package A includes |
| 90 | +PCRE2, it must respect the condition, but if package B is software that |
| 91 | +includes package A, the condition is not imposed on package B unless it uses |
| 92 | +PCRE2 independently. |
