Actually, even among this, only lppl1.3a and lppl1.2 are on the
license-list.html at gnu.org. I mailed them a few weeks back asking them
to consider adding the other licenses to the list. They replied saying
that license review is a resource intesive project, and that they will
*eventually* have it on the list. That may not be any time soon, I
guess.
