/*! \page formulas Including formulas 

Doxygen allows you to put \f$\mbox{\LaTeX}\f$ formulas in the
output (this works only for the HTML and \f$\mbox{\LaTeX}\f$ formats, 
not for the man page output). To be able to include formulas (as images)
in the HTML documentation, you will also need to have the following tools
installed
<ul>
<li>\c latex: the \f$\mbox{\LaTeX}\f$ compiler, needed to parse the formulas. 
    To test I have used the teTeX 0.9 distribution.
<li>\c dvips: a tool to convert dvi files to postscript files 
    I have used version 5.86 from Radical Eye software for testing.
<li>\c gs: the ghostscript interpreter for converting postscript files 
    to bitmaps. I have used Aladdin Ghostscript 5.10 for testing.
</ul>

There are two ways to include formulas in the documentation.
<ol>
<li>Using in-text formulas that appear in the running text. 
    These formulas should be put between a pair of \\f\$ 
    commands, so
\verbatim
  The distance between \f$(x_1,y_1)\f$ and \f$(x_2,y_2)\f$ is 
  \f$\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\f$.
\endverbatim results in:

  The distance between \f$(x_1,y_1)\f$ and \f$(x_2,y_2)\f$ is 
  \f$\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\f$.
<br>
<li>Unnumbered displayed formulas that are centered on a separate line.
    These formulas should be put between \\f\[ and \\f\] commands.
    An example:
\verbatim
  \f[
    |I_2|=\left| \int_{0}^T \psi(t) 
             \left\{ 
                u(a,t)-
                \int_{\gamma(t)}^a 
                \frac{d\theta}{k(\theta,t)}
                \int_{a}^\theta c(\xi)u_t(\xi,t)\,d\xi
             \right\} dt
          \right|
  \f]
\endverbatim
  results in:
  \f[
    |I_2|=\left| \int_{0}^T \psi(t) 
             \left\{ 
                u(a,t)-
                \int_{\gamma(t)}^a 
                \frac{d\theta}{k(\theta,t)}
                \int_{a}^\theta c(\xi)u_t(\xi,t)\,d\xi
             \right\} dt
          \right|
  \f]
</ol>
Formulas should be valid commands in \f$\mbox{\LaTeX}\f$'s math-mode.

\warning Currently, doxygen is not very fault tolerant in recovering 
from typos in formulas. It may have to be necessary to remove the
file <code>formula.repository</code> that is written in the html directory to 
a rid of an incorrect formula
