. Modify mdb-export to handle different delimiters/options
. Get automake working
. Check out text file unixODBC driver to see if it can be adapted to use

. Straighten out which functions in libmdb are meant to be used and which   ones should be static.
. Create an API reference for libmdb (maybe some man pages).
. Sargs need to support all datatypes
. Need a way to express logical relationships between sargs (tree)
