Thanks very much for your diligence here.

I looked into it, and Debian calls this the "Perforce" license.  The
"copyright" file for Debian's 'boost' package includes the following
lines:

--8<---------------cut here---------------start------------->8---
License: Perforce
 License is hereby granted to use this software and distribute it
 freely, as long as this copyright notice is retained and modifications
 are clearly marked.
 .
 ALL WARRANTIES ARE HEREBY DISCLAIMED.
--8<---------------cut here---------------end--------------->8---

<https://metadata.ftp-master.debian.org/changelogs//main/b/boost1.67/boost1.67_1.67.0-13+deb10u1_copyright>

Maybe this should be added to (guix licenses) as 'perforce', or perhaps
'perforce-jam'?

Thoughts?
