A common mistake is to revoke your own access control rights in a
    directory. If you have access control rights in a parent directory,
    you can regain the access rights that you lost.
    
    Example: If user ALICE has [RCWEMFA] in USR:ALICE/ but accidentally
	revoked access control in the subdirectory PROJECTS (let's just
	say she now has [RF] in USR:ALICE/PROJECTS/), she would not be
	able to simply use grant to get the rights back because she has
	insufficient rights.

    To recover access control:

    1. Check which groups you are in (or equivalent to).
	WHOAMI /S
    2. Pick a group and grant access rights to that group in the parent.
	GRANT A TO EVERYONE FOR USR:ALICE
    3. You should now have access control in the subdirectory.
	CD PROJECTS
    4. Remove the trustee which caused the problem.
	TLIST
	REMOVE ALICE FROM USR:ALICE/PROJECTS
    5. Remove the rights of the group from the parent directory.
	REMOVE EVERYONE FROM USR:ALICE
