 \subsubsection*{Basic server structure}
   
 The Web server is started by calling the httpd procedure, which takes
-one required and two optional arguments:
+one argument, a \ex{httpd\=options}-record:
 
-\defun{httpd}{path-handler \ovar{port working-directory}}{\noreturn}
+\defun{httpd}{options}{\noreturn}
 \begin{desc}
-  The server accepts connections from the given \semvar{port}, which
+  The \semvar{options} can be set via the various options-transformers
-  defaults to 80. The server runs with the \semvar{working-directory} set to
+  that can be found in the \ex{httpd\=make\=options}-structure:
-  the given value, which defaults to \ex{/usr/local/etc/httpd}.
+  \ex{with\=port}, \ex{with\=root\=directory}, \ex{with\=fqdn},
+  \ex{with\=reported-port}, \ex{with\=path\=handler},
+  \ex{with\=server\=admin}, \ex{with\=simultaneous-requests}, that set
+  the port the server is listening to, the root-directory of the
+  server, the FQDN of the server, the reported-port \FIXME{What does
+    reported-port do?}, the path-handler of the server (see below),
+  the mail-address of the server-admin and the maximum number of
+  simultaneous handled requests. The port defaults to 80, the root
+  directory defaults to ``\ex{/}'' and the mail address of the
+  server-admin defaults to
+  ``\ex{sperber@\ob{}informatik.\ob{}uni\=tuebingen.\ob{}de}''.
+  \FIXME{Why does the server admin mail address have
+    sperber@informatik... as default value?}All other options default
+  to \sharpf.
+
+  For example
+  \begin{code}
+(httpd (with-path-handler 
+        (rooted-file-handler "/usr/local/etc/httpd")
+        (with-root-directory "/usr/local/etc/httpd")))
+  \end{code}
+  
+  starts the server on port 80 with
+  ``\ex{/usr/\ob{}local/\ob{}etc/\ob{}httpd}'' as root directory and
+  let it serve any files out from this directory. Note that
+  \ex{with\=root\=directory} is nested in \ex{with\=path\=handler}.

   The server's basic loop is to wait on the port for a connection from
   an HTTP client. When it receives a connection, it reads in and
