As far as I know, the Perl version of SimFactory does not use the .ini file format. However, there are several files around in the repository which make it look like it does:
MacBook:simfactory ian$ find . -name "*.ini" ./cdb.ini ./mdb/abe.ini ./mdb/ac.ini ./mdb/bp.ini ./udb.example.ini
as well as an "inifiles" directory. This is confusing as when you first check it out, you don't know which files to customise.
I propose that these files be removed.
