This is not necessary.
The E/R files call 'rel', which is just 'put'ting some information (i.e.
relation objects) to the involved class(es). You can easily do that
manually, on the fly.
'*Dbs' is - as we discussed in the other thread - only needed upon DB
creation (then the sizes matter), and when 'pool' opens a DB (then only
the length of '*Dbs' matters).
All other side effects of 'dbs' again involve properties of relation
objects (i.e. the file number where to create new objects, and the block
size used by the index trees), which again can be done manually.
