[cups] Fwd: `ipptool` + `ippserver`: Differences between "ippsample"- and "cups"-GitHub repos?

[Kurt Pfeifle]

What are the major current feature differences (if any) between the
versions of `ipptool` and `ippserver` if built from the two GitHub
repositories of *ippsample* (owned by the PWG) and *cups* (owned by Apple),
both mainly developed by Mike?

Is the *ippsample* version going to develop more features and diverge more
from its parent in *cups* than is currently the case?

Will the same-named utils (ippfind, ipptool, ippserver) one day be removed
from the CUPS source tree and continue to live only in the ippsample repo?

(I noticed that in *cups* there is are no `ippproxy`, `ipptransform` and
`ipptransform3d` utilities.)
