Crazy Mac Filenames --- Cleanup Code Needed

[Roger.E.Eller at sealedair.com]

I have at least 30,000 Mac files and folders that have filenames 
containing non-cross-platform-friendly filenames. Many of them even 
include dates with the / character. This makes it difficult to use the Rev 
rename command to change it to a better name because the / is seen as a 
folder delimiter. Does anyone have a ready-made script that cleans up such 
filenames? These files are also buried within several subfolders, so it 
needs to work recursively. I owe you much gratitude if you can help.
