[hv] From the documentation: *This package provides objects for the programmable traversal of directory hierarchies. * While traversing down a directory, there are times when you encounter one that is not accessible. While the documentation stated the package will ignore those directories by default. In reality, my sample script crashed. Curious, I dug into the source code and found what might be a bug. I posted the problem and a work-around solution on http://stackoverflow.com/questions/17633681/how-to-handle-permission-denied-when-using-fileutiltraverse%|%StackOverflow%|% <> Package | Tcllib | File
