A SPECIAL REMARK ABOUT LICENSE CONDITIONS
We would certainly like to continue to distribute the documented
sources freely, but currently we have the situation that we cannot
continue in this programmer-friendly way as before.
Thus, we have uglified some of the files in the distribution: these
are the graph layout modules. These files are not anymore readable
for human being, but they are readeable for the compiler. Thus you
can compile the sources as before, but you cannot find out anymore
how the details of the layout algorithms work.
This is a compromise. I think this is a better solution than to
distribute binaries, because the users still can adapt the tool to
their computer system. (In the layout modules, normally no adaption
is necessary). Further, we did not spent too much time with
uglification, thus the result should not be too ugly ;-)
VCG is currently in main, but is it distributable at all? The GPL doesn't
consider this source, IIRC.
