Please help me to understand how that would work. If I can modify a file I can 
delete its contents - after all, that is what modification permits. If I can 
modify the contents of a file by deleting it, how does that differ from not 
being able to delete the file? Perhaps I am really dense here.

Under UNIX write capability means deletion capability. How does one implement 
modification without deletion in a UNIX environment?
