% File: srcltx.sty (version 001.000)
% ==========
%
% This package was written by the author of WinEdt Shell to implement
% a source file tracking and DVI "SRC" specials for LaTeX.
%
% This package comes with no guarantees and no reserved rights.
% You can use or modify this file at your own risk.
% ************************************************************************
% NOTE: TeX commands are case sensitive. You have to use uppercase
% \Input to take advantage of this package
%
% This file should be placed in a directory where your LaTeX is
% looking for inputs.
%
% If you are writing a book with WinEdt and LaTeX simply
% include this file and use \include{mychapter} command...
% This way all the necessary specials for DVI Search and
% Inverse Search are inserted in your DVI File.
%
% WinEdt will be able to track Errors from your LOG file.
%
% * NOTE: Some TeX implementations add the file type to the "\jobname".
% In that case the definition of the "\MainFile" should be modified to:
%
% \def\MainFile{\jobname} instead of \def\MainFile{\jobname.tex}.
%
%
% Your LaTeX thesis document may look something like this:
%
%\documentclass[12pt]{report}
%\usepackage[centertags]{amstex}
%\usepackage{thesis,newlfont,amsthm}
%\usepackage[active]{srcltx}
%%No src specials are written when loading the package by
%%\usepackage[inactive]{srcltx}
%
% .... Preamble ....
%
%\begin{document}
%
% .... Title, Author etc. ....
%
%\WinEdt{?0000} % Do not process any Errors (Overful/Underful Boxes)
%\beforepreface
%\WinEdt{?1111} % Process All Types of Errors from here on
%\include{ABS}
%\include{ACK}
%\afterpreface
%\include{chapter0}
%\include{chapter1}
%\include{chapter2}
%\include{chapter3}
%\bibliographystyle{amsplain}
%\bibliography{xbib}
%\end{document}
%
% To remove SRC Specials from the dvi file compile the source
% after inserting \SRCOKfalse immediately after
% the \usepackage{srcltx} directive...
%
% This package supports nested \Input commands...
% File extension should be specified in \Input!
