Message:

Extra Phind functionality: any special parameter values inserted into the
gdbm database by the phind.pm classifier are extracted and set as macros.
This lest us distinguish between multiple phind classifiers for one
collection (with the phindnumber macro, and will ultimately be used to pass
appearance parameters like colours and fonts from the from the collect.cfg
file all theway to the Java pplet.
