Good question. That was me refactoring the DigestCache and Dict::SQLite 
perldocs to allow for other kinds of dictionaries. 

I added that paragraph on the basis of the doc/data-structures.txt, but I think 
you're right - that's probably a pre-inventory-db document, and those comments 
apply now to the inventory db, not the digest cache. I'll correct.
