Hi Bart

I think the problem is probably with me, not using the diff command
correctly :)

But, here's the command I would use to test if the patch will apply:

patch --dry-run --verbose \
[path_to]/BlenderManual/appendices/licenses/appendix_licenses.xml \
[path_to]appendix_licenses.xml.diff

where [path_to] is replaced to suit your own system.

Hope that's right.

Eric
