% This file contains some predicates that are defined in BIM-prolog and
% not in SWI-prolog (or at least not with the same meaning).
% In case a predicate has a different meaning in SWI-prolog
% and in proLog by BIM renaming is done.
% Remark that some predicates are only partially covered, feel free to add.

% modified by Jan Wielemaker:
%
% - Added module-declaration
% - Mapped writeClause/2 onto portray_clause/1
% - deleted the my... (SWI-Prolog can redefine predicates)
%
% modified by Henk Vandecasteel:
%
% - Added some missing predicates in the module-declaration.
% - Index/2 of proLog by BIM is transformed to index/1.
% - Fixed some bugs in the record-database-predicates.

% modified by Jan Wielemaker at Aug 10, 2006
%
% - Fixed module header
% - Keep erase/1 and recorded/3 local as they break applications
