+and semantics are as close as possible to those of the Perl 5 language.

+     Regular expression support is provided by the PCRE library package,

+     ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/
+
+   should also be given in the documentation. However, this condition is not
+   intended to apply to whole chains of software. If package A includes PCRE,
+   it must acknowledge it, but if package B is software that includes package
+   A, the condition is not imposed on package B (unless it uses PCRE
+   independently).
+
+3. Altered versions must be plainly marked as such, and must not be
+   misrepresented as being the original software.
+
+4. If PCRE is embedded in any software that is released under the GNU

+   then the terms of that licence shall supersede any condition above with
+   which it is incompatible.
+
+The documentation for PCRE, supplied in the "doc" directory, is distributed
+under the same terms as the software itself.
