File Attributes
===============

   When you issue an `ls -l' shell command on a file, it gives you
information about the size of the file, who owns it, when it was last
modified, etc.  These are called the "file attributes", and are
associated with the file itself and not a particular one of its names.

   This section contains information about how you can inquire about and
modify the attributes of a file.
