The index file format was originally defined that way by the Staden 
package, and also used by EMBL/EBI CD-ROM indexing and by utilities at 
the Sanger Centre/Institute.

The dbi* index files have two problems - they cannot store file 
positions larger than 2Gb aqnd they do not allow duplicate primary 

We may remove them in a future release - but for smaller databases many 
users seem to find them useful still.
