If this directory contains a PHP FastCGI executable called
<architecture>-<os>/php-cgi.sh] or <architecture>-<os>/php-cgi.exe,
the PHP/Java Bridge library tries to call it via a /bin/sh wrapper 
(see launcher.sh) or via a "launcher.exe" when the server 
or the web context starts:


   internet 
  clients 
        \                    
         \ jsp/servlet/php req.                     .
           \                                        .
            ---- :8080 -- J2EE AS                   .
           /                 |                      .
          |                  |                      .
          |                  ---- servlet         /------ :9667

UNIX: If /bin/sh is available and the php-cgi supports the -b flag,
the library executes the following command during startup:

REDIRECT_STATUS="200" \
X_JAVABRIDGE_OVERRIDE_HOSTS="/" \
PHP_FCGI_CHILDREN="5" \
PHP_FCGI_MAX_REQUESTS="5000" \
arch-os/launcher.sh arch-os/php-cgi -c php-cgi.ini -b 127.0.0.1:9667


WINDOWS: If /bin/sh is not available or if the php-cgi.exe does not
support the -b flag, the library executes the following command during
startup:

set REDIRECT_STATUS "200"
set X_JAVABRIDGE_OVERRIDE_HOSTS "/"
set PHP_FCGI_CHILDREN "5" 
set PHP_FCGI_MAX_REQUESTS "5000"
launcher.exe PHP-CGI NAMED-PIPE PHP-OPTIONS
