[GNC] How to manage multiple accounts (as in separate gnucash databases)?

[Chris Green]

I have several gnucash accounts files (sqlite databases in my case)
spread around my system.  When I go to a specific directory and run
GnuCash I just want it to see only the database[s] in that directory.

Is there a way I can tell gnucash to forget about all previous files
it has opened?  As it is I get presented with a 'memory' of other
accounts which can be very confusing unless I'm very careful with file
naming.

The --nofile option tells gnucash not to open the last accounts
database, it helps a little, but I really want it to forget more!
