This is totally non-free, alas. It does not allow for modification of
the software, prohibits commercial sale (thus making it impossible to
distribute as part of a Debian DVD or CD set) and contains a serious
use restriction (against "nontrivial military significance", whatever
*that* means).

That bit's OK.

I'm a bit unclear as to what this means. The author seems to think
that the notice itself is the "copyright", so when he says the subject
"is subject to this copyright only", I assume he means "subject to
this copyright *notice* only". That's probably OK, though it could
cause some compatibility problems if combined with GPLed software.

I don't think any clarification is needed for inclusion in non-free,
assuming that the "no sale for profit" wording is OK for non-free.
