  The well known JGEX program became open source a few years ago, but
seemingly, further development of the program can only be done without the
original authors. In our project, we are looking at whether it is possible to
continue such a large project as a newcomer without the involvement of the
original authors. Is there a way to internationalize, fix bugs, improve the
code base, add new features? In other words, to save a relic found in the attic
and polish it into a useful everyday tool.
