an is compiled</h3>
<p>Stan is compiled in two steps, first a model is translated to templated C++ and then to a platform-specific executable. Stan, unlike BUGS, allows the user to directly program in C++, but we do not describe how to do this in this Stan manual (see the getting started with C++ section of https://mc-stan.org for more information on using Stan directly from C++).</p>
