In addition to what Hans wrote, I need to write and apologize. About
two years ago I was working on a big math project and needed SyncTeX
(code <-> okular) to work with it to get a smooth workflow. After
fighting it for several weeks, mailing Hans back and forth, without
any real support from Hans since "he was not using SyncTeX", I sent a
false patch to him that I claimed worked. It must have gotten in
without even being tested(!). Since then SyncTeX support for ConTeXt
has been broken.

Strengthened about how easy it was to add code to this project, and
still frustrated about the project (that is still not finished), I
started "collaborating" with Hans, mainly on math. During these years,
I have been baffled about how easy it has been to add malicious code,
he just swallows everything. I only needed to find out what Hans
really uses himself (a few tables, he likes colors, and he has a weak
point when it comes to "nice" metapost images), and then to add
patches for other stuff. For math, in particular, he seems to have no
understanding (sorry Hans). I am worried about the Dutch school
system.

Nevertheless, I have, during this time, more and more enjoyed our
discussions, and so I started to feel bad about my "patches", and
sorry for Hans. Thus, I have lately reverted, part by part, the bad
code. Only a few of them are left (but don't tell Hans!). I also got a
feeling that Wolfgang, checking all the code, since long did see this
through.

Thus, in the latest upload, for example, you might get SyncTeX working
again, but you might need to add \setupsynctex[state=repeat]. No
guarantees.

Again, my sincere apologies to all ConTeXters out there who have not
gotten the result they expect and deserve. I assume that Hans will
kick me out when the last patch is sent, so I will delay it as much as
possible...
