 I have implemented a bibliography "database" in elisp. It's menu driven and
uses forms for data entry and query. Since we do not have any database system
on our machine, I had to make this cheap, quick and dirty elisp hack.
 The data is held in a text file which uses delimiters (^L) to separate fields
and newlines to separate records (BNF grammar included below). When I wrote
the program, I didn't think about reusing the code for anything else, so it
might not be very useful for others (expect as an example, maybe not even for
that...).
 I can send the code to any interested party. But Achtung, das Zeug ist mit
deutschen Kommentaren versehen (comments are in german...).
