**  mod_proctitle.c -- Apache sample proctitle module
**  [Autogenerated via ``apxs -n proctitle -g]
**
**  To play with this sample module first compile it into a
**  DSO file and install it into Apache's modules directory
**  by running:
**
**    $ apxs -c -i mod_proctitle.c
**
**  Then activate it in Apache's httpd.conf file for instance
**  for the URL /proctitle in as follows:
**
**    #   httpd.conf
**    LoadModule proctitle_module modules/mod_proctitle.so
**
**  Then after restarting Apache via
**
**    $ apachectl restart
