Well, it is not satisfactory for me, yet.  It is still "almost almost"
and needs some wizardies to work.  At least the doc should be updated
and maybe a manifest file with the correct TeX packages.  I mean we
have modular texlive and we recommend to use it but we do not use it
for our own infrastructure and then we rely on the BIG texlive
package.  Hum?! :-)

They should be documented at least.  (How to find them is another story. ;-))


All the best,
