           Summary: nrwt outputs empty files for wdiff output if wdiff is
                    not installed
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P3
         Component: Tools / Tests
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: kbalazs at webkit.org
                CC: ojan at chromium.org, dpranke at chromium.org


It would be nice to avoid generating these useless files. Furthermore, I think we should print a warning message if wdiff is not installed, otherwise folks will likely not notice this useful feature at all (on Linux it's usually not installed by default).
