/*! \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$\mbox{\LaTeX}\f$ output, 
not for the RTF nor 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
