-- minimal version also used in Hugs. AR 2/12/2002.
-- databases for customizable commands. AR 21/11/2001
-- for: grammar parsers, grammar printers, term commands, string commands
-- idea: items added here are usable throughout GF; nothing else need be edited
-- they are often usable through the API: hence API cannot be imported here!
-- Major redesign 3/4/2002: the first entry in each database is DEFAULT.
-- If no other value is given, the default is selected.
-- Because of this, two invariants have to be preserved:
-- ** no databases may be empty
-- ** additions are made to the end of the database
-- these are the databases; the comment gives the name of the flag
