    In the latter case, OzTeX requires you to specify ":fonts:tfm:*".

    Nothing more than the above options.  I'm a devotee of KISS!

    This is the only extra option I'd (very reluctantly) consider.

>Any other comments:

    As I've indicated, I prefer as simple a directory structure as possible,
    but one that is practical when it comes to storing lots of files.
    In my view that means a small number of directories (possibly just one)
    that must be explicitly listed.  These directories can contain at most
    one level of subdirectories.  Anything more and my brain starts to hurt.
