%%   This is file `mcode.sty'
%%
%%   It is supposed to help you easily include MATLAB source code
%%   into LaTeX document,  but have it nicely highlighted, using
%%   the great listings package.
%%
%%   PLEASE NOTE that this package does nothing but save you from
%%   figuring out some configurations  in setting up the LISTINGS
%%   package. ALL the work is done by that package!  Thus, please
%%   refer your questions to the listings package documentation.
%%
%%   Usage: You have three ways of including your MATLAB code. As
%%   environment,  as inline object and directly from an external
%%   file.
%%
%%   1) Environment:
%%
%%          \begin{lstlisting}
%%             YOUR CODE HERE
%%          \end{lstlisting}
%%
%%
%%   2) Inline object*:
%%
%%          Bla bla \mcode{CODEFRAGMENT} bla bla.
%%
%%
%%   3) Include external file (in environment form)
%%
%%          \lstinputlisting{YOUR-FILE.m}
%%
%%
%%   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
%%
%%   - autolinebreaks  if you want  the package to  automatically
%%          wrap your  code.  This is buggy as it  may well break
%%          break syntax and it  doesn't work well with comments.
%%          You REALLY should wrap your code manually.
%%
%%   - useliterate   if you want  some characters / relations  in
%%          your code to be replace with something more readable.
%%          Example: ~= becomes $\neq$, >= becomes $\geq$,  delta
%%          becomes $\delta$ and so on.
%%
%%   - 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).
%%
%%   For example, you may use \usepackage[numbered,framed]{mcode}
%%   in your document preamble.
%%   
%%   * If you want to place  some inline code in a footnote,  use
%%   \mcodefn{} instead (this will reduce the font size a bit).
%%
%%   Note:  Inside code blocks you  can escape to LaTeX text mode
%%   using §...§.  For ex. §text and some math: $x^2$§,  which is
%%   especially  useful  in comments  for putting  nicely typeset
%%   equations etc.  To get the same  colour/style as in the rest
%%   of the comment use \mcommentfont, i.e. §\mcommentfont $x^2$§
%%
%%   To change the font used,  edit the first line in the "custo-
%%   mise below" section.  And feel free to  edit other things as
%%   well.  Refer to the documentation of the listings package to
%%   see what  else you could do.  If an extra small font  is re-
%%   quired,  use  {\fontfamily{pcr}\fontsize{3}{4.6}\selectfont}
%%   in the definition of \lstbasicfont.
