% docparts allows you to directly typeset a part of a document
% and have the main document typeset with the proper \includeonly
% statement automagicaly inserted.

% 
% docparts is really useful if your editor can invoke latex on the 
% document you are editing: this will compile only the part of the 
% document you are working on instead of triggering a LaTeX 
% "missing \begin{document}" error.
% 
% docparts is not really a package since it cannot be used
% with \usepackage. It must be \input at the beginning of each
% part of a document.

% 
% Each part should be put into the main document using LaTeX \include 
% commands. For instance, main.tex should look like:
%   \documentclass[...]{...}
%   ...
%   \usepackage{docparts}
%   ...
%   \begin{document}
%   ...
%   \include{part1}
%   \include{part2}
%   ...
%   \end{document}
%   
% Each partx.tex file should start with:
%   \input{docparts.sty}
%   \docpart{main}{partx}
% where <partx> is the name of the part.
% 
% "latex main" will typeset the full document, but "latex part2" will 
% typeset only part2 by issuing an \includeonly{part2} command and 
% inputing main.tex.
% 
% When you are working on <partx> of a document, just typeset <partx>. 
% You do not need to edit the main document to add an \includeonly 
% statement.
% If your text editor is able to send the current document to LaTeX, 
% you do not need to switch to the main document window to typeset 
% the current part.
