jbovlaste is a dictionary editing interface by Jay Kominek, massively updated by Robin Lee Powell, now in full production.

Brammo also created a program to create a dict database out of a database generated by jbovlaste, lojtexdict. "Dict" in that sentence is not an abbreviation but connotes a type of software which creates "dict datbases." Using this download involves prerequisites of a technical nature.
