+SYNOPSIS

+
+DESCRIPTION
+  mdb-schema is a utility program distributed with MDB Tools. 
+
+  It produces DDL (data definition language) output for the given database. This can be passed to another database to create a replica of the original access table format.
+
+OPTIONS
+  -T            Single table option.  Create schema for this table only.
+  backend	Specifies target DDL dialect. Supported values are access, sybase, oracle, and postgres. If not specified the generated DDL will be in access format.

+AUTHORS
+  The mdb-schema utility was written by Brian Bruns
