% \begin{abstract}\noindent
% This package provides source special insertion into DVI files,
% allowing to jump from the DVI file to the \file{.tex} source
% and back (given a DVI viewer that supports this).  Additionally,
% it provides hooks for error tracking from the \file{.log} file
% for the WinEdt shell.
% \end{abstract}
% 
% \tableofcontents
% 
% \section{Warning}
% 
% \textbf{Source specials may alter the paragraph spacing
% in your document. Always process the final version of your document with
% this package commented out, or deactivated:}
% |\usepackage[inactive]{srcltx}|.
% 
% \section{Usage}
% To use the package with \LaTeX, put the line
% 
% |\usepackage{srcltx}|
% 
% \noindent
% into the preamble of your document.  For \TeX, use
% 
% |\input srctex.sty|
% 
% \noindent
% instead.  This will insert source specials at every
% start of a paragraph of your document and at every math environment
% (see the `Options' section below for how to customize this).  A source
% special is only inserted if there hasn't already been one on the same
% source input line.
% 
% For editors and DVI viewers that support it, source specials can be used for
% `inverse search' between the (La)\TeX\ source and the DVI file:
% The \file{.dvi} viewer can open a text editor with the file
% (and line) of the corresponding place in the \file{.tex} source
% (also called `reverse search'), and the editor can invoke the previewer
% with the corresponding place in the \file{.dvi} file (`forward search').
% Examples for DVI previewers supporting this are: The Windows viewers YAP and Dviwin,
% and the Unix viewers xdvi(k) (versions $\geq$ 22.38) and KDVI (KDE $\geq$ 3.0).
% Editors supporting inverse search are e.g. WinEdt, (X)Emacs, nedit and vim.
% 
% The package was originally written for use with the WinEdt shell, and
% it offers some special features to customize WinEdt's error
% tracking. These are shown in the example in figure~\ref{ex} on page~\pageref{ex}.
% 
% The specials inserted by this package have the following format, which should
% be compatible with all DVI viewers:
% 
% \begin{tabular}{@{}l@{}}
% |\special{src:|\textit{line-number}\textvisiblespace\textit{filename}|}|
% \end{tabular}
% 
% 
% \subsection{Options}
% 
% The following options are only available for the \LaTeX2e\ version of
% this package. Unless noted otherwise, the Plain \TeX\ version \package{srctex.sty}
% has a command |\SRC|$\langle$\texttt{foo}$\rangle$ for each option
% $\langle$\texttt{foo}$\rangle$, e.g. |\SRCnopar| replaces the
% `\texttt{nopar}' option.
% \begin{descr}
% 
% \item[\texttt{active}\slash\texttt{inactive}]
% 	  With the \texttt{inactive} option, source specials are disabled, but
% 	  the source file tracking for WinEdt is still active.
% 	  
% 	  The \texttt{active} option is only useful to override
% 	  a global \texttt{inactive} option.
% 
% 	  For \package{srctex.sty}, use \Com{SRCOKtrue} and \Com{SRCOKfalse}
% 	  instead.
% 
% \item[\texttt{nowinedt}] Turn off the source file tracking used by WinEdt (the
% 	  |:<+ |\texttt{\textit{filename}} line in the output every time
% 	  an input file is opened, and the |:<-| line when it's closed again).
% 
% \item[\texttt{dviwin}] Use specials in a format suitable for dviwin
% 	   (without a space between the line number and the filename).
% 
% \item[\texttt{debug}] Print debugging information on current
% 	  input file and the input file stack.
% \end{descr}
% The following options can be used to turn off source specials for certain
% environments; try these options if you encounter problems with the default behaviour:
% \begin{descr}
% \item[\texttt{nopar}] Don't hook into |\everypar|.
% 
% \item[\texttt{nomath}] Don't hook into |\everymath|.
% 
% %BROKEN \item[\texttt{nodisplay}] Don't hook into |\everydisplay|.

% 
% \subsection{Commands}
% \begin{descr}
% 
% \item[\Com{SRCOKtrue}, \Com{SRCOKfalse}] You can use these commands to
% 	   activate\slash deactivate source specials at any place in your
% 	   document, e.g. when you experience problems with some special
% 	   constructions (see also `Bugs and Restrictions' in section
% 	   \ref{sec:bugs}).
% 	   
% \item[\Com{Input}\marg{filename}] In order to keep track
% 	   of the current filename, the \LaTeX\ commands
% 	   \Com{include}\marg{filename} and \Com{input}\marg{filename}
% 	   are overloaded (note the braces enclosing the filename argument).  The
% 	   \Com{input} command where the filename can be specified
% 	   without any delimiters is a \TeX\ primitive command that can
% 	   not be overloaded easily.  Therefore the package provides an
% 	   alternative command |\Input| which you should use in Plain
% 	   \TeX\ instead of \Com{input} if you want the specials in such
% 	   files to point to the correct filename.  For \LaTeX, you
% 	   should always use the version with braces:
% 	   \Com{input}\marg{filename}.  \emph{Note}: For Winedt, you will
% 	   also need to specify the file name extension (e.g.
% 	   \file{.tex}) in the argument of this command.
% 
% \item[\Com{MainFile}] By default, the \TeX\ primitive |\jobname| contains the name of the
% 	   ``main'' TeX file, without the filename extension `\file{.tex}'.
% 	   Accordingly, |\MainFile| is defined as |\jobname.tex|. 
% 	   If your implementation does already add the extension
% 	   to |\jobname|, you should redefine this command as follows:
% 
% 	   \noindent\begin{tabular}{@{}l@{}}
% 	   |\def\MainFile{\jobname}|
% 	   \end{tabular}
% \end{descr}
% 
% \section{Bugs and Restrictions}\label{sec:bugs}
% 
% Since this macro package overloads some internal \LaTeX\ commands, it
% is not as robust as one might wish, and may interact badly with other
% packages. Furthermore, the spacing may be altered by using the
% package; for example, with the \file{amsmath} documentation \file{amsldoc.tex},
% the bibliography is shifted from the bottom of page 31 to page 32.
% Therefore you should comment out the package or disable it with the
% \texttt{inactive} option when preparing the final version of your document.
% 
% A somewhat more robust method of inserting source specials is to use \TeX\
% (the program) instead of a macro solution. Some \TeX\ implementations
% provide a command line option for this.\footnote{%
% E.g. a `\file{-src}' option is available in Mik\TeX\ from version 1.20 upwards,
% or in te\TeX\ from version beta-20011103 or teTeX-2.0 upwards. See the manual of your
% \TeX\ implementation for details on this.}
% You can still load \package{srcltx.sty} with the `\texttt{inactive}' option to enable
% the WinEdt error tracking features.
% 
% This section lists known incompatibilities with other packages and workarounds for these.
% If you know of any other problems, please send a bug report to
% \href{mailto:stefanulrich@users.sourceforge.net}{\texttt{<stefanulrich@users.sourceforge.net>}}.
% \begin{description}
% \item[{\normalfont\package{soul.sty}:}] Active source specials inside
% 	  the soul tokenization routine may lead to a `reconstruction failed'
% 	  error. As a workaround, the internal command |\SOUL@| is overloaded
% 	  by \package{srcltx}. With the Plain \TeX\ version, \package{srctex.sty}
% 	  needs to be loaded \emph{after} \package{soul.sty} to make this work.
% \item[{\normalfont\package{syntax.sty}:}] This style does extensive parsing
% 	  of the input inside its `grammar' environment, which is incompatible
% 	  with \package{srcltx.sty}.
% \end{description}
% 
% \section{Related Packages}
% 
% Heiko Oberdiek's \package{vpe.sty} provides source specials for
% forward search in PDF files. To our knowledge there exists no
% implementation for reverse search with PDF viewers, or inverse search
% in Postscript documents.
% 
% \section{History}
% 
% This package was originally written by A.~Simonic, the WinEdt Shell
% author, to implement a source file tracking and DVI source specials
% for \TeX. D.~P.~Carlisle and B.~K.~Horn have contributed bug
% fixes. Further changes and conversion to \file{ltxdoc} format by S.~Ulrich.
% Thanks for patches and suggestions to: A.~Cherepanov, J.~Rawnsley, D.~Kastrup,
% D.~Arseneau and M.~S.~Gr\o nsleth.
