this works only with a 'per entry compression' and with 'one file per entry'
databanks. Examples are pdb, hssp. The file seq.dat.Z for
swissprot could be uncompressed on the fly for the indexing. But then
for doing entry retrieval the whole seq.dat.Z needs to be uncompressed for
accessing even a single entry.

Any input is very welcome. You could print out the manual, annotate it, eg,
mark the passages that are not understandable and send it to us.
