-<!-- FIXME, example of Stdio.Port here -->
+<h2>A more complex example - a simple www server</h2>
+
+</h2>For you who are not familiar with WWW (World Wide Web), it works by using
+client program which will fetch files from remote servers when asked.
+Usually by clicking a pitcure or text. This example is a program for the
+server which will send files to any computer that requests them. The
+protocol used to send the file is called HTTP. (HyperText Transfer Protocol)
+<p>
+Usually WWW involves HTML. HTML (HyperText Markup Language) is a way to
+write documents with embedded pictures and links to other pages. These
+links are normally displayed underlined and if you click them your WWW-
+browser will load whatever document that link leads to.
+<p>
+<pre>
+ #!/usr/local/bin/pike
+
+ /* A very small httpd capable of fetching files only.
+ * Written by Fredrik H�binette as a demonstration of Pike.
+ */
+
+ inherit Stdio.Port;
+</pre>
+We inherit Stdio.Port into this program so we can bind a TCP socket to accept
+incoming connection. A socket is simply a number to separate communications
+to and from different programs on the same computer.
+<p>
+Next are some constants that will affect how uHTTPD will operate. This uses
+the preprocessor directive #define. The preprocessor is the first stage in
+the compiling process and can make textual processing of the code before
+it is compiled. As an example, after the first define below, all occurances
+of 'BLOCK' will be replaced with 16060.
+<pre>
+
+ /* Amount of data moved in one operation */
+ #define BLOCK 16060
+
+ /* Where do we have the html files ? */
+ #define BASE "/usr/local/html/"
+
+ /* File to return when we can't find the file requested */
+ #define NOFILE "/user/local/html/nofile.html"
+
+ /* Port to open */
+ #define PORT 1905
+</pre>
+A port is a destination for a TCP connection. It is simply a number on the
+local computer. 1905 is not the standard port for HTTP connections though,
+which means that if you want to access this WWW server from a browser you
+need to specify the port like this: http://my.host.my.domain:1905/
+<p>
+Next we declare a class called output_class. Later we will clone one
+instance of this class for each incoming HTTP connection.
+<p>
+<pre>
+ class output_class
+ {
+ inherit Stdio.File : socket;
+ inherit Stdio.File : file;
+</pre>
+Our new class inherits Stdio.File twice. To be able to separate them
+they are then named 'socket' and 'file'.
+<p>
+<pre>
+ int offset=0;
+</pre>
+Then there is a global variable called offset which is initalized to zero.
+(each instance of this class will have it's own instance of this variable,
+ so it is not truly global, but..)
+Note that the initalization is done when the class is cloned. (or
+instanciated if you prefer C++ terminology)
+<p>
+Next we define the function write_callback(). Later the program will go
+into a 'waiting' state, until something is received to process, or until
+there is buffer space available to write output to. When that happens a
+callback will be called to do this. The write_callback() is called when
+there is buffer space available. In the following lines 'void' means that
+it does not return a value. Write callback will be used further down as a
+callback and will be called whenever there is room in the socket output
+buffer.
+<pre>
+
+ void write_callback()
+ {
+ int written;
+ string data;
+</pre>
+The following line means: call seek in the inherited program 'file'.
+<pre>
+
+ file::seek(offset);
+</pre>
+Move the file pointer to the where we want to the position we want to read
+from. The file pointer is simply a location in the file, usually it is where
+the last read() ended and the next will begin. seek() can move this pointer
+to where we want it though.
+<p>
+<pre>
+ data=file::read(BLOCK);
+</pre>
+Read BLOCK (16060) bytes from the file. If there are less that that left to
+read only that many bytes will be returned.
+<p>
+<pre>
+ if(strlen(data))
+ {
+</pre>
+ If we managed to read someting...
+<p>
+<pre>
+ written=socket::write(data);
+</pre>
+ ... we try to write it to the socket.
+<p>
+<pre>
+ if(written >= 0)
+ {
+ offset+=written;
+ return;
+ }
+</pre>
+ Update offset if we managed to write to the socket without errors.
+<p>
+<pre>
+ werror("Error: "+socket::errno()+".\n");
+ }
+</pre>
+ If something went wront during writing, or there was nothing left to read
+ we destruct this instance of this class.
+<p>
+<pre>
+ destruct(this_object());
+ }
+</pre>
+ That was the end of write_callback()
+<p>
+
+ Next we need a variable to buffer the input received in. We initialize it
+ to an empty string.
+<pre>
+
+ string input="";
+</pre>
+ And then we define the function that will be called when there is something
+ in the socket input buffer. The first argument 'id' is declared as mixed,
+ which means that it can contain any type of value. The second argument is
+ the contents of the input buffer.
+<p>
+<pre>
+ void read_callback(mixed id,string data)
+ {
+ string cmd;
+
+ input+=data;
+</pre>
+Append data to the string input. Then we check if we have received a
+a complete line yet. If so we parse this and start ouputting the file.
+<p>
+<pre>
+ if(sscanf(input,"%s %s%*[\012\015 \t]",cmd,input))
+ {
+</pre>
+This sscanf is pretty complicated, but in essense it means: put the
+first word in 'input' in 'cmd' and the second in 'input' and return 2
+if successfull, 0 otherwise.
+<p>
+<pre>
+ if(cmd!="GET")
+ {
+ werror("Only method GET is supported.\n");
+ destruct(this_object());
+ return;
+ }
+</pre>
+If the first word isn't GET print an error message and terminate
+this instance of the program. (and thus the connection)
+<pre>
+
+ sscanf(input,"%*[/]%s",input);
+</pre>
+Remove the leading slash.
+<p>
+<pre>
+ input=combine_path(BASE,input);
+</pre>
+Combine the requested file with the base of the HTML tree, this gives
+us a full filename beginning with a slash. The HTML tree is the
+directory on the server in which the HTML files are located. Normally
+all files in this directory can be accessed by anybody by using a WWW
+browser. So if a user requests 'index.html' then that file name is first
+added to BASE (/home/hubbe/www/html/ in this case) and if that file exists
+it will be returned to the browser.
+<pre>
+
+ if(!file::open(input,"r"))
+ {
+</pre>
+Try opening the file in read-only mode. If this fails, try opening NOFILE
+instead. Opening the file will enable us to read it later.
+<p>
+<pre>
+ if(!file::open(NOFILE,"r"))
+ {
+</pre>
+If this fails too. Write an error message and destruct this object.
+<p>
+<pre>
+ werror("Couldn't find default file.\n");
+ destruct(this_object());
+ return;
+ }
+ }
+</pre>
+Ok, now we set up the socket so we can write the data back.
+<pre>
+
+ socket::set_buffer(65536,"w");
+</pre>
+Set the buffer size to 64 kilobytes.
+<p>
+<pre>
+ socket::set_nonblocking(0,write_callback,0);
+</pre>
+Make it so that write_callback is called when it is time to write more
+data to the socket.
+<p>
+<pre>
+ write_callback();
+</pre>
+Jump-start the writing.
+<pre>
+ }
+ }
+</pre>
+That was the end of read_callback().
+<p>
+
+This function is called if the connection is closed while we are reading
+from the socket.
+<pre>
+ void selfdestruct() { destruct(this_object()); }
+
+</pre>
+This function is called when the program is instanciated. It is used
+to set up data the way we want it. Extra arguments to clone() will be
+sent to this function. In this case it is the object representing the
+new connection.
+<p>
+<pre>
+ void create(object f)
+ {
+ socket::assign(f);
+</pre>
+We insert the data from the file f into 'socket'.
+<p>
+<pre>
+ socket::set_nonblocking(read_callback,0,selfdestruct);
+</pre>
+Then we set up the callback functions and sets the file nonblocking.
+Nonblocking mode means that read() and write() will rather return that
+wait for I/O to finish. Then we sit back and wait for read_callback to
+be called.
+<p>
+<pre>
+ }
+</pre>
+End of create()
+<p>
+<pre>
+ };
+</pre>
+End of the new class.
+<pre>
+
+</pre>
+Next we define the function called when someone connects.
+<p>
+<pre>
+ void accept_callback()
+ {
+ object tmp_output;
+</pre>
+This creates a local variable of type 'object'. An object variable can
+contain a clone of any program. Pike does not consider clones of different
+programs different types. This also means that function calls to objects
+have to be resolved at run time.
+<p>
+<pre>
+ tmp_output=accept();
+</pre>
+The function accept clones a /precompiled/file and makes this equal to the
+newly connected socket.
+<p>
+<pre>
+ if(!tmp_output) return;
+</pre>
+If it failed we just return.
+<p>
+<pre>
+ output_class(tmp_output);
+</pre>
+Otherwise we clone an instanec of 'output_class' and let it take care of the
+connection. Each clone of output_class will have it's own set of global
+variables, which will enable many connections to be active at the same
+time without data being mixed up. Note that the programs will not actually
+run simulataneously though.
+<p>
+<pre>
+ destruct(tmp_output);
+</pre>
+Destruct the object returned by accept(), output_class has already copied
+the contents of this object.
+<p>
+<pre>
+ }
+
+</pre>
+Then there is main, the function that gets it all started.
+
+<pre>
+ int main(int argc, string *argv)
+ {
+ werror("Starting minimal httpd\n");
+</pre>
+Write an encouraging message to stderr.
+<pre>
+
+ if(!bind(PORT, accept_callback))
+ {
+ werror("Failed to open socket (already bound?)\n");
+ return 17;
+ }
+
+</pre>
+Bind PORT and set it up to call accept_callback as soon as someone connects
+to it. If the bind() fails we write an error message and return the 17 to
+indicate failiure.
+<pre>
+
+ return - 17; /* Keep going */
+</pre>
+If everything went ok, we return -17, any negative value returned by main()
+means that the program WONT exit, it will hang around waiting for events
+instead. (like someone connecting)
+<pre>
+ }
+</pre>
+That's it, this simple program can be used as the basis for a simple
+WWW-server. Note that today most WWW servers are very complicated programs,
+and the above program can never replace a modern WWW server.

-<a name=preprocessor>
-Pike has a builtin C-style preprocessor. The preprocessor reads the source
-before it is compiled and removes comments and expands macros. The preprocessor
-can also remove code depending on an expression that is evaluated when you
-compile the program. The preprocessor helps to keep your programming abstract
-by using defines instead of writing the same constant everywhere.
+This module is used to achive better compatibility with older versions of
+Pike. It can also be used for convenience, but I would advice against it
+since some functions defined here are much slower than using similar
+functions in other modules. The purpose of this section in the manual is
+to make it easier for the reader to understand code that uses the Simulate
+module, not to encourage the use of the Simulate module.
<p>
-It currently works similar to old C preprocessors but has a few extra features.
-This chapter describes the different preprocessor directives. This is
-what it can do:
+Simulate inherits the Array, Stdio, String and Process modules, so
+importing he Simulate module also imports all identifiers from these
+modules. In addition, these functions are available:

+<H1>The preprocessor</h1>
+<a name=preprocessor>
+Pike has a builtin C-style preprocessor. The preprocessor reads the source
+before it is compiled and removes comments and expands macros. The preprocessor
+can also remove code depending on an expression that is evaluated when you
+compile the program. The preprocessor helps to keep your programming abstract
+by using defines instead of writing the same constant everywhere.
+<p>
+It currently works similar to old C preprocessors but has a few extra features.
+This chapter describes the different preprocessor directives. This is
+what it can do:

+<hr noshade size=1>

+<tt>#!<br>
+</tt>
+<p>
+<dt><b> <font size=+1>D</font><font size=-1>ESCRIPTION</font></b><dd>
+This directive is in effect a comment statement, since the
+preprocessor will ignore everything to the end of the line.
+This is used to write unix type scripts in Pike by starting
+the script with
+<p>#!/usr/local/bin/pike

+</tt>
+<p>
+<dt><b> <font size=+1>D</font><font size=-1>ESCRIPTION</font></b><dd>
+The simplest way to use define is to write
+<p><dl><dt><dd>#define <identifier> <replacement string><br>
</dl>
<p>which will cause all subsequent occurances of 'identifier' to be
replaced with the replacement string.

+call this function with a mapping containing the following elements:
+<p>
+<center>
+<table>
+<tr><td>year</td><td>The number of years since 1900</td></tr>
+<tr><td>mon</td><td>The month</td></tr>
+<tr><td>mday</td><td>The day of the month.</td></tr>

+<tr><td>min</td><td>The number of minutes after the hour</td></tr>
+<tr><td>sec</td><td>The number of seconds after the minute</td></tr>
+<tr><td>isdst</td><td>If this is 1, daylight savings time is assumed</td></tr>
+<tr><td>tm</td><td>The timezone (-12 <= tz <= 12)</td></tr>
