<h2>About the parser</h2> 

<p>
Many applications require the parsing of <strong>mathematical expressions</strong>.
The main objective of this library is to provide a fast and easy way of
doing this. <strong>muParser</strong> is an extensible high performance
<strong>math parser</strong> library written in <a href="http://www.cplusplus.com/">C++</a>. It works 
by transforming a mathematical expression into bytecode and precalculating constant 
parts of the expression.

The library was designed with portability in mind and should compile on every
standard compliant C++ compiler. Wrapper for <strong>C</strong> and <strong>C#</strong> 
exist. The parser archive contains ready to use project and makefiles files for a variety of 
platforms. The code runs on both <strong>32 bit</strong> and 
<strong>64 bit</strong> architechtures and has been tested using MS VC++ V8.0 
and GCC V4.4.1. Code samples are provided in order to help you understand its 
usage. The library is <strong>open source</strong> and distributed under 
the <a href="http://www.opensource.org/licenses/mit-license.php">MIT license</a>.

A project like muParser requires permanent maintanence in order to adopt to new platforms, new compiler version and for fixing bugs. So if you are using the library and find it useful i would like to encourage you to make a donation in order to help keeping the project up to date. I can officially guarantee that you <strong>make my day</strong> by donating even a small amount of money. In a way this is a "Wow the people actually really appreciate what i'm doing" kind of thing and that's whats driving me and ultimately this is what is keeping this project alive.
