Excellent news.

    The build is done using CMake, so I'm not sure about the best way to
    integrate it into the current autotools-based toolchain.

As far as I can imagine, it is impossible. (Also, FWIW, I have no
interest in spending any time thinking about cmake in any way, so if
it's going to happen, someone else will have to work on it.)

    so the binaries for most relevant platforms are already available (and
    could be made available at particular commits/branches to match what

It seems reasonably possible to import your lmtx binaries into TL (along
with the corresponding sources of course, just as a tarball in
Master/source). A lot more possible than doing anything with cmake in
the build tree, at least.  The missing platforms aren't a problem as far
as I'm concerned.

To make the formats, do users then run "context --generate", as with
mkiv?  (At least as far as I know that's what is done with luatex/mkiv.)
That is, nothing more needs to happen at TL installation time? That
would be good.

More generally, though: I was under the impression that lmtx is Hans's
playground and as such is constantly changing. So what is the gain
in having a particular build frozen into a TL image? Just wondering. -k
