This is a note from Peter Flach (in Holland) about running the debugger
under Quintus Prolog. It may be useful to others porting it.


There were a few small problems running it under Quintus,
such as some newlines occurring where they shouldn't, an existentially
quantified variable in bagof using ';' (semicolon) instead of '~' (accent
circonflexe; BTW this may be caused by the email connection between the
UK and Holland, since I remember seeing that before), and renaming some
user-defined predicates (read and write).
