Tntnet has a template-language called ecpp similar to PHP, JSP or Mason, where you can embed c++ code inside a HTML page to generate active content. The ecpp files are precompiled to C++ classes called components and compiled and linked into a shared library. This process is done at compiletime. The web server Tntnet needs only the compiled component library.

This module attempts to work around those issues.
