BCSUtils is a BCC-enhanced version of ACSUtils. It has exactly the same functions and constants as ACSUtils, so all ACSUtils documentation also works for BCSUtils.
BCSUtils is not a separate project. ACSUtils and BCSUtils are produced from the same source code and always stay in sync.
Strict typing for all functions and constants.
All functions are in the BCSUtils namespace.
Just include bcsutils.bcs instead of acsutils.acs.
