In this chapter, we've looked in depth at the default PHPTemplate theme engine. You should now have an awareness of the key files involved in a PHPTemplate theme and some appreciation of how those files interact. The discussion of the order of precedence among various theme files lays down a fundamental principle. You have seen example of how to override default theme files by placing alternative files inside the theme directories.
In this chapter, we also spoke about alternative theme engines and noted that although the range of choices is now limited, hopefully we will see more options soon.
