Might be a problem at my site.  I now ran cvs update again several
times, and each time it claims to update the same files.  I doubt that
anything is updated at all.  The directory

 > pgf/generic/pgf/libraries/graphdrawing/lua

doesn't exist.  However, everything is fine after a fresh checkout.
Seems that I'm doing something wrong.  Maybe I'm too much accustomed
to svn end expect that cvs works the same way.

It *is* great!  I recently prepared a tiny demo file, just to show how
easily problems can be solved with LuaTeX:


With LuaTeX one can do much more, but I deliberately kept this file
tiny, simple, and the source code comprehensible.  Even with the
highly sophisticated math macros provided by pgf, I wouldn't even
consider to program something like that in TeX.

In real life I already use lua + pgfplots quite frequently.  I can't
provide an example because I don't want to expose my bank account
here.  However, pgfplots is incredibly slow because all calculations
are done in TeX, thus I'm interesting in a pgf math library written in

As an aside: I just ran

  pdftotext -layout luatab.pdf

Wow! I'm deeply impressed!  Seems that we need PDF viewers only if we
are interested in microtypography.

Microsoft isn't the answer. Microsoft is the question, and the answer is NO.
