Good question. There are 530 C files...

I will follow the debian analysis at

http://packages.debian.org/changelogs/pool/main/n/netpbm-free/netpbm-free_10.0-12.2/libnetpbm10.copyright

and write down my findings here for future reference.

There is

fiasco: no license information inside netpbm, but it is distributed on its own as gpl2+, see

https://github.com/megatherion/Fiasco/blob/master/README

mdatopbm: gpl2+

pamstretch: gpl2+

pbmpage, pbmtoppa: This appears to be gpl2 only. The C files state:

* Copyright (c) 1998 Tim Norman. See LICENSE for details

And LICENSE is GPLv2.

So I will stop here and push as gpl2.
