/**
  *
  * For files not on the acl.read or acl.write list, applets cannot
  *
  *    1 - check for the existence of the file
  *    2 - check the file type
  *    3 - check if the file is a directory
  *    4 - check the timestamp when the file was last modified
  *    5 - check the file's size
  *    6 - create a directory
  *    7 - rename the file
  *    8 - list the files in this file (as if it were a directory)
  *    9 - check read
  *   10 - check write
  *
  * Before: 
  *   Assumes /var/mail/root is a file
  *   Assumes there isn't a directory named /var/mail/testdir
  *
  * After:
  *   The directory /var/mail/testdir may have been created,
  *   if you ran this test from the appletviewer with /var/mail
  *   on your acl.write list.   If that's the case, then you 
  *   should manually delete the test directory /var/mail/testdir 
  *   before running this test again.
