I've put yet another tds version up at
  ftp://tug.org/tex/tds.tar.gz
  ftp://tug.org/tex/tds/   (including tds.dvi)
  http://tug.org/tds/

There's a bad page break at Section 3.1, but I thought people should see
the text before worrying about that.

I'll probably read this over once more before making an official
release, but anyway.

Here are the diffs.  If anyone has a better idea for a word besides
`Extensions', I'd love to hear it :-).

+ \subsection{Extensions}
+ \label{sec:Extensions}
+ 
+ New programs that are extensions of old ones shall use a new top-level
+ directory name for their extension-specific input files.  The new
+ directory shall have the same general structure as the top-level
+ directory of the original program, and the new program almost certainly
+ should search the original top-level directory.
+ 
+ For example, several variants of \TeX{} that recognize additional
+ commands have been released.  Input files that use these new commands
+ cannot be placed in the top-level \path|tex| directory, since the
+ original \TeX{} program cannot read them.  So they must go in a new
+ directory, with the same package structure as \path|tex| (see
+ Section~\ref{sec:Macros}).
+ 
+ Using e-\TeX{} as an example, we have the following:
+ 
+ \begin{itemize-squeeze}
+ 
+ \item A new top-level (in \path|texmf|) directory \path|etex|.
+ 
+ \item Since e-\TeX{} is an extension of \TeX{}, \path|texmf/etex|
+ follows the same conventions as \path|texmf/tex|.
+ \path|texmf/etex| contains only e-\TeX{}-specific files.
+ 
+ \item e-\TeX{} searches first \path|texmf/etex|, then \path|texmf/tex|.
+ 
+ \end{itemize-squeeze}
+ 
+ These same principles hold for PDF\TeX{}, Omega, and (most probably)
+ future variants of \TeX{} or \MF{}.
