HISTORY
mdb-schema first appeared in MDB Tools 0.1.AUTHORS
The mdb-schema utility was written by Brian Bruns and others.BUGS
Relationships and other features may not be supported by all databases. Access datatypes are mapped to their closest counterparts in the target backend. This may not always yield an exact fit.
