[Bug 28186] New: uninstaller has no proper usage message

http://bugs.winehq.org/show_bug.cgi?id=28186

Summary: uninstaller has no proper usage message
           Product: Wine
           Version: 1.3.26
          Platform: x86
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: programs
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

First uninstaller uses WINE_ERR() to tell the user he got the usage wrong (like
when he forgets a parameter). That's wrong as this is not a Wine error.

Second it never prints a usage message thus leaving the user guessing.

Finally if run in the wineconsole the user will see no output at all but that's
a somewhat independent issue (see bug 28185).
