looking for a PD database library for *nix

[Randy Orrison]

I'm looking for a simple database manager library.  My requirements are:
	public domain	(NOT copyright/left/trade secret)
	multiple keys
	concurrent access	(multiple readers, locking of multiple writers)
	multiple entries with a single key	(dbm is out)
	easily portable

Any pointers would really be appreciated.

	Many Thanks!
