Does anyone know about a utility, that can automatically detect and remove unrequired units from the uses
clause?
Preferably it ..
Try using the "Uses Unit Cleaner" Wizard from CnPack you can download from here
Another option is use ICARUS.
ICARUS is a small subset of Pascal Analyzer. It parses Delphi or Borland Pascal source code and generates a list of unneeded unit references in your uses lists
ICARUS from Peganza does something similar.
