\section{Usage:}

In the document preamble, ``\verb+\excludeonly{+\meta{aaa}\verb+,+\meta{bbb}\verb+}+'' will prevent files
\texttt{\meta{aaa}.tex} and \texttt{\meta{bbb}.tex} from being typeset by \cmd{\include}\marg{aaa} and \cmd{\include}\marg{bbb}. 
If both \cmd{\includeonly} and \cmd{\excludeonly} are used, then only the files
permitted by both declarations are used:
%
\begin{flushleft}
\verb+\includeonly{+\meta{aaa}\verb+,+\meta{bbb}\verb+}+\\
\verb+\excludeonly{+\meta{bbb}\verb+,+\meta{ccc}\verb+}+
\end{flushleft}
%
results in only \meta{aaa} being included.
This behavior contradicts the name ``exclude only'' but the name is 
desirable anyway to show the relationship with \cmd{\includeonly}.

In case it is actually desireable that \cmd{\excludeonly} lives up
to its name, and causes \emph{all} parts to be included, except those
explicitly listed for exclusion, there is an \opt{[only]} package option
%
\begin{verbatim}
\usepackage[only]{excludeonly}
\end{verbatim}
%
The effect of this is to override any \cmd{\includeonly} commands.


\section{Conflicts:}

This package redefines the internal \cmd{\@include} command, so it could
conflict with other redefinitions.  Known conflicts are with document 
classes ``\cls{paper.cls}'' and ``\cls{thesis.cls}'' by Wenzel Matiaske.

A different method for implementing \cmd{\excludeonly} would be to 
redefine \cmd{\@setckpt} to compile a file-inclusion list (\cmd{\@partlist})
that accounts for exclusions.  Surprisingly, several packages
redefine \cmd{\@setckpt}, so this alternative would have more conflicts.
