Debugging is twice as hard as writing the code in the first place. 
Therefore, if you write the code as cleverly as possible, you are,
by definition, not smart enough to debug it.

The Apache/Perl integration project brings together the full power
of
the Perl programming language and the Apache HTTP server. This
is
achieved by linking the Perl runtime library into the server and
providing an object oriented Perl interface to the server's C language
API.
These pieces are seamlessly glued together by the `mod_perl' server
plugin, making it is possible to write Apache modules entirely
in
Perl. In addition, the persistent interpreter embedded in the server
avoids the overhead of starting an external interpreter program
and
the additional Perl start-up (compile) time.
