+Tepal is a Template Parsing Library, written in C.

+## Description
+
+It's origin lies in my unhappieness with PHP, JSP and other
+languages designed for web-development. Lately i learned a little
+about template system and worked a little with smarty and after a
+while i got the idea that if one wants to seperate program logic
+from display logic it is also possible to write you application
+in C as i prefer. The FastCGI interface is as fast or even faster than
+the PHP interface. The only thing needed is a library that does the
+same things as smarty, set template variables, parse a template and
+write the result.
+
+Well, it turns out that this only thing was more work than i first
+thought, especially because i never wrote an interpreter or compiler
+before. And i had not college courses on that issue too. So i had to
+find out everything by my own. Thanks go to the excellent documentation
+of flex and bison and the Telos GmbH that published a simple interpreter.
+
+While i was writing this I recognised that it might be usefull at other
+things too. Everything that can be created by a cleartext template
+and some application logic can be created with this lib.
