            Bug ID: 142034
           Summary: [Win] Make build logs more legible by reducing noise
    Classification: Unclassified
           Product: WebKit
           Version: 528+ (Nightly build)
          Hardware: PC
                OS: All
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebCore Misc.
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: bfulgham at webkit.org

Our Windows build logs produce a tremendous amount of boilerplate output and detailed build state that makes it very difficult to find and understand why the build has failed.

We can improve things as follows:

1. Update our batch file (Windows CMD files) to use the '@' character as the first character on each line. This will prevent these lines from being echoed into our build logs.
2. Pass the '/Q' flag to our invocations of CMD so that they run silently. This will reduce another set of output that we generally do not care about.
3. Pipe the output of XCOPY to "NUL". This will hide the file copy state, but we have not generally found these messages to be helpful when debugging build errors, even when they have been caused by files not being copied.
