- * This is equivalent to
- *    cd /var/www
- *    httpd -p 80 -c /etc/httpd.conf -r "Web Server Authentication"
+ * Typical usage:
+ *   for non root user
+ * httpd -p 8080 -h $HOME/public_html

+ *
  *
  * When a url contains "cgi-bin" it is assumed to be a cgi script.  The
  * server changes directory to the location of the script and executes it
  * after setting QUERY_STRING and other environment variables.  If url args
  * are included in the url or as a post, the args are placed into decoded
  * environment variables.  e.g. /cgi-bin/setup?foo=Hello%20World  will set
- * the $CGI_foo environment variable to "Hello World".
+ * the $CGI_foo environment variable to "Hello World" while
+ * CONFIG_FEATURE_HTTPD_SET_CGI_VARS_TO_ENV enabled.
  *
  * The server can also be invoked as a url arg decoder and html text encoder
  * as follows:
- *  foo=`httpd -d $foo`           # decode "Hello%20World" as "Hello World"
- *  bar=`httpd -e "<Hello World>"`  # encode as "&#60Hello&#32World&#62"
+ *  foo=`httpd -d $foo`             # decode "Hello%20World" as "Hello World"
+ *  bar=`httpd -e "<Hello World>"`  # encode as "%3CHello%20World%3E"
  *
  * httpd.conf has the following format:
- 
-ip:10.10.         # Allow any address that begins with 10.10.
-ip:172.20.        # Allow 172.20.x.x
-ip:127.0.0.1      # Allow local loopback connections
-/cgi-bin:foo:bar  # Require user foo, pwd bar on urls starting with /cgi-bin
-/:admin:setup     # Require user admin, pwd setup on urls starting with /
 
- *
- * To open up the server: 
- * ip:*              # Allow any IP address
- * /:*               # no password required for urls starting with / (all)
- *

+ * Inetd - Internet super-server
+ *
+ * This program invokes all internet services as needed.
+ * connection-oriented services are invoked each time a
+ * connection is made, by creating a process.  This process
+ * is passed the connection as file descriptor 0 and is
+ * expected to do a getpeername to find out the source host
+ * and port.
+ *
+ * Datagram oriented services are invoked when a datagram
+ * arrives; a process is created and passed a pending message
+ * on file descriptor 0.  Datagram servers may either connect
+ * to their peer, freeing up the original socket for inetd
+ * to receive further messages on, or ``take over the socket'',
+ * processing all arriving datagrams and, eventually, timing
+ * out.  The first type of server is said to be ``multi-threaded'';
+ * the second type of server ``single-threaded''.
+ *
+ * Inetd uses a configuration file which is read at startup
+ * and, possibly, at some later time in response to a hangup signal.
+ * The configuration file is ``free format'' with fields given in the
+ * order shown below.  Continuation lines for an entry must being with
+ * a space or tab.  All fields must be present in each entry.
+ *
+ *      service name                    must be in /etc/services
+ *      socket type                     stream/dgram/raw/rdm/seqpacket
+ *      protocol                        must be in /etc/protocols
+ *      wait/nowait[.max]               single-threaded/multi-threaded, max #
+ *      user[.group]                    user/group to run daemon as
+ *      server program                  full path name
+ *      server program arguments        maximum of MAXARGS (20)
