Re: internationalization support?

I'm supportive of i18n efforts (being non-native English speaker myself).

There are some potential issues I see with this, though.

It is very common that less-used OCaml libraries become unmaintained
or abandoned. This in turn becomes a burden on Unison maintainers (who
have very little resources available). This is already becoming a
problem with the GUI, for example.

It looks like ocaml-gettext has received recent updates, but this only
after a long period of silence. Maybe it's a non-issue but it may be
cause for concern. Camomile (optional) seems to be abandoned, even
though there seems to be some attempt at keeping it alive (but it's
still out of date).

There used to be a WIP of i18n support at
https://urldefense.com/v3/__https://github.com/bcpierce00/unison/branches__;!!IBzWLUs!X5w2rZbM7zkcpXucW9-KkSZyHPcfgGt2bvHa37BG8Lb8UlrHyj4y30oUwG6tjewxv3B5kQ7JCo96PBjQZEn1Zc5n8Uk$  in a separate branch but
since it had been abandoned for years, I think the branch was deleted.

Having non-complete platform support is not a problem in general.
Building the code without gettext support should also be easy enough
with a simple stub in place of ocaml-gettext. There is an example at
https://urldefense.com/v3/__https://github.com/gildor478/ocaml-gettext/blob/master/doc/reference-manual.md*adding-gettext-support-without-depending-on-ocaml-gettext__;Iw!!IBzWLUs!X5w2rZbM7zkcpXucW9-KkSZyHPcfgGt2bvHa37BG8Lb8UlrHyj4y30oUwG6tjewxv3B5kQ7JCo96PBjQZEn1e9f6qGw$ 
. The build scripts will become more complicated, for sure, but that's
under our control and acceptable if the benefits are considered
desirable (build scripts being rather complicated is in part due to
wanting to have strong support of many platforms, with sometimes very
different dependencies).

Reviewing and collaborating on the PR will probably take a very long
time. Don't take that as a sign of lack of interest. It's a sign of
lack of resources.

Since there is a severe lack of maintainer resources and i18n support
does come with some maintenance burden (even if it turns out to be
minimal), I would like to know beforehand if there is sufficient
interest by users/translators. unison-hackers list will probably not
answer that question (unison-users list perhaps could but is likely
not representative of non-English speaking users). Remember that years
ago there already was an attempt at i18n (also using gettext if I
remember correctly) but that did not succeed. (Not being involved back
then, I don't know the details.)
