%%   This is file `mcode.sty'
%%
%%   It is supposed to help you easily include MATLAB source code
%%   into LaTeX document, but have it nicely highlighted, unsing
%%   the great listings package.
%%
%%   Usage: Include your MATLAB source code by using
%%
%%     \begin{lstlisting}
%%       YOUR CODE HERE
%%     \end{lstlisting}
%%
%%   or as an inline object via \mcode{YOURCODE}.
%%
%%   For your convenience, this package has the following options:
%%
%%   -  bw  if you intend to print the document (highlighting done
%%          via text formatting (bold, italic) and shades of gray)
%%   
%%   -  numbered  if you want line numbers
%%
%%   -  framed  if you want a frame around the source code blocks
%%
%%   -  final  if you have ``gloablly'' set the draft option, the
%%          listings package will not output the code at all.  to
%%          force it to do so anyway, load this package with the
%%          final option (passes the ``final'' on to listings).
%%
%%   Example of use:  \usepackage[numbered,framed]{mcode}
%%   in your document preamble.
%%   
%%   Note: inside code blocks you can 'escape' to LaTeX math mode
%%   by using § YOUR LATEX CODE §, which is especially useful in
%%   comments...
%%
%%   Another feature of the listings package is that you can re-
%%   place certain strings by LaTeX strings; this is used for
%%   some relation symbols, see below...
%%
%%   Mat Odijk pointed this out, you may include entire m-files
%%   using the command \lstinputlisting{YOUR-FILE.m}. Thanks for
%%   the tip!
%%
%%   Feel free to edit things, and refer to the listings package 
%%   documentation for more infos.
%%
%%   If you have any questions, feel free to ask:  floz@gmx.de
%%
%%   Usolved problem:  long lines of code that are wrapped with
%%   '...', and things thereafter being comments.....
%%   but i'm working on it ;-)
