I need the URL for where the German government or an agency maintains the
most current German per diem rate tables for T & E reimbursements. 
This is from the prospective of a German based traveler being
reimbursed by the German government for travel.  This is not to just
get the rates right now.  This is to be able to stay current on the
rates at all times.

I think you want to want the Bundesreisekostengesetz  (Federal travel expense law).

Here is one site with the currently relevant text:
http://www.jugendstiftung-civitas.org/downloads/reisekosten.pdf

Since the law was updated this year, I am sure this is the present status.

Here is another site that will probably be updated for any changes:
http://bundesrecht.juris.de/brkg_2005/index.html

Since your question is so specific, I am assuming that the German text
will be satisfactory for you, but if you need a quick explanation of
any part, please let me know with a comment here.
Regards, Myoarin

I don't need the rules.  I need the table of rates e.g. Paris, France 
20 euros for meals, 150 euros for lodging, 3 euros for incidentals,
london ......, Madrid....
