This is probably FAQ #1 and its annoying as hell to have to
     answer it over and over and over and over and over again.
     We use suEXEC and suPHP!  What this means is that the tools
     you have access to under your SDF membership are the tools
     you can use in your website scripting.

     To make use of SSI, be sure to use .shtml as your filename

     Need to see php4 options?  Create a file called 'test.php'
     in your webdirectory, and put the following inside:

     How about CGI?
     If you know how to ask the question, you better know how to
     make use of the facilities.  Giving a detailed tutorial is
     beyond the scope of this FAQ, however, very simple examples
     may show up here. For instance:

     If you want to create a simple CGI, you don't need to use
     PERL, you can do it the UNIX way in ksh!  (PS, PERL != CGI)

     # My silly.cgi
     echo Content-type: text/html
     echo ""
     echo "
my silly hello world.

     To create powerful CGIs using LISP, you can use OpenLISP on
     SDF by simply:

     #!/usr/pkg/uxlisp/uxlisp -quiet
     ; My powerful.cgi
     (print "Content-type: text/html")
     (print "")
     (print "
my powerful hello world.

     For more information and a tutorial on using LISP on SDF
     for the web, see http://lisp-p.org

     While we don't directly support 'ASP' you can convert any 
     ASP format file to a PHP file using 'asp2php'

     Yes, use the extension '.cgi' for a script to be executed by
     the webserver.  You can run 'mkhomepg -p' to set proper file
     permissions after you have uploaded or created new files. Also,
     you don't need a 'cgi-bin' or whatever like some sites have.
     Its not necessary!  CGIs can be run from any directory within
     your web directory.

     If you have read this answer and its of no help, rather than
     pestering all the other users, how about going off and reading
     a book on PHP, PYTHON, LISP .. whatever ..
