File System Standard

[Gregory Bell <winston@atlantic.net>]

There was some mention of the file system made not long ago so I decided
to
get the latest version of the fsstd  and read it over.  Here is an
extract of the document.
NOTE: programs in parens ( ) are located there as a strong suggestion
by the standard.

DIRECTORY TREE STRUCTURE:

Most of these directories are selfexplainitory the only major change in
the addition of the OPT directory.
The Opt directory is to be used when the user adds new programs to the
system (i.e. Gimp).
