Hi, While reviewing the licenses of the code for a possible inclusion into Debian, I say something that caught my attention: most of the files in `qsrc/` are licensed under GPL-2+ or MIT, but one file, namely `qcsrc/lib/p99.qh`, is licensed under the old QPL 1.0 which is notoriously [incompatible with the GPL](https://www.gnu.org/licenses/license-list.html#QPL) It means that products derived from code under both the GPL and the QPL cannot be redistributed. And it seems this file is actively used during the build; this is unfortunate, to say the least. It seems that the original P99 project [has moved](https://gitlab.inria.fr/gustedt/p99/-/commit/e6ef447dd0e10ea24ef68bfec1e5dd586a0c0af2) to the Apache-2.0 license (which is GPL-3 compatible) some years ago, so there may be a way out... Sorry for the bad news; if I missed something and I'm completely wrong, please point me to the right direction :-) Best regards, Sébastien
