+## W LANGUAGE
+
+### Overview
+
+The goal of the W language is to be simple, efficient, and robust.
+It comes with a compiler that generates *p-code* binary code,
+compatible with any platform.
+A W p-code executor will be available for Linux and other operating systems.
+W programs will be callable from other programs, much like a plugin system.
+The *lwf* utility is available for formatting source code.
+
+To get started, here is a first example program:
+
+``` w
+; The famous Hello World in W
+begin hello
+   echonl "Hello world !"
+except
+end
+```
+
+# Installation
+Installation from the official repositories for Debian/Ubuntu-based systems:
+```

+/*
+exemples :
+
+1. A simple request with no data on stdin, and a successful response:
+{FCGI_BEGIN_REQUEST,   1, {FCGI_RESPONDER, 0}}
+{FCGI_PARAMS,          1, "\013\002SERVER_PORT80\013\016SERVER_ADDR199.170.183.42 ... "}
+{FCGI_PARAMS,          1, ""}
+{FCGI_STDIN,           1, ""}
+
+    {FCGI_STDOUT,      1, "Content-type: text/html\r\n\r\n<html>\n<head> ... "}
+    {FCGI_STDOUT,      1, ""}
+    {FCGI_END_REQUEST, 1, {0, FCGI_REQUEST_COMPLETE}}
+2. Similar to example 1, but this time with data on stdin. The Web server chooses to send the parameters using more FCGI_PARAMS records than before:
+
+{FCGI_BEGIN_REQUEST,   1, {FCGI_RESPONDER, 0}}
+{FCGI_PARAMS,          1, "\013\002SERVER_PORT80\013\016SER"}
+{FCGI_PARAMS,          1, "VER_ADDR199.170.183.42 ... "}
+{FCGI_PARAMS,          1, ""}
+{FCGI_STDIN,           1, "quantity=100&item=3047936"}
+{FCGI_STDIN,           1, ""}
+
+    {FCGI_STDOUT,      1, "Content-type: text/html\r\n\r\n<html>\n<head> ... "}
+    {FCGI_STDOUT,      1, ""}
+    {FCGI_END_REQUEST, 1, {0, FCGI_REQUEST_COMPLETE}}
+3. Similar to example 1, but this time the application detects an error. The application logs a message to stderr, returns a page to the client, and returns non-zero exit status to the Web server. The application chooses to send the page using more FCGI_STDOUT records:
+
+{FCGI_BEGIN_REQUEST,   1, {FCGI_RESPONDER, 0}}
+{FCGI_PARAMS,          1, "\013\002SERVER_PORT80\013\016SERVER_ADDR199.170.183.42 ... "}
+{FCGI_PARAMS,          1, ""}
+{FCGI_STDIN,           1, ""}
+
+    {FCGI_STDOUT,      1, "Content-type: text/html\r\n\r\n<ht"}
+    {FCGI_STDERR,      1, "config error: missing SI_UID\n"}
+    {FCGI_STDOUT,      1, "ml>\n<head> ... "}
+    {FCGI_STDOUT,      1, ""}
+    {FCGI_STDERR,      1, ""}
+    {FCGI_END_REQUEST, 1, {938, FCGI_REQUEST_COMPLETE}}
+4. Two instances of example 1, multiplexed onto a single connection. The first request is more difficult than the second, so the application finishes the requests out of order:
+
+{FCGI_BEGIN_REQUEST,   1, {FCGI_RESPONDER, FCGI_KEEP_CONN}}
+{FCGI_PARAMS,          1, "\013\002SERVER_PORT80\013\016SERVER_ADDR199.170.183.42 ... "}
+{FCGI_PARAMS,          1, ""}
+{FCGI_BEGIN_REQUEST,   2, {FCGI_RESPONDER, FCGI_KEEP_CONN}}
+{FCGI_PARAMS,          2, "\013\002SERVER_PORT80\013\016SERVER_ADDR199.170.183.42 ... "}
+{FCGI_STDIN,           1, ""}
+
+    {FCGI_STDOUT,      1, "Content-type: text/html\r\n\r\n"}
+
+{FCGI_PARAMS,          2, ""}
+{FCGI_STDIN,           2, ""}
+
+    {FCGI_STDOUT,      2, "Content-type: text/html\r\n\r\n<html>\n<head> ... "}
+    {FCGI_STDOUT,      2, ""}
+    {FCGI_END_REQUEST, 2, {0, FCGI_REQUEST_COMPLETE}}
+    {FCGI_STDOUT,      1, "<html>\n<head> ... "}
+    {FCGI_STDOUT,      1, ""}
+    {FCGI_END_REQUEST, 1, {0, FCGI_REQUEST_COMPLETE}}

+exemples :
+
+1. A simple request with no data on stdin, and a successful response:
+{FCGI_BEGIN_REQUEST,   1, {FCGI_RESPONDER, 0}}
+{FCGI_PARAMS,          1, "\013\002SERVER_PORT80\013\016SERVER_ADDR199.170.183.42 ... "}
+{FCGI_PARAMS,          1, ""}
+{FCGI_STDIN,           1, ""}
+
+    {FCGI_STDOUT,      1, "Content-type: text/html\r\n\r\n<html>\n<head> ... "}
+    {FCGI_STDOUT,      1, ""}
+    {FCGI_END_REQUEST, 1, {0, FCGI_REQUEST_COMPLETE}}
+2. Similar to example 1, but this time with data on stdin. The Web server chooses to send the parameters using more FCGI_PARAMS records than before:
+
+{FCGI_BEGIN_REQUEST,   1, {FCGI_RESPONDER, 0}}
+{FCGI_PARAMS,          1, "\013\002SERVER_PORT80\013\016SER"}
+{FCGI_PARAMS,          1, "VER_ADDR199.170.183.42 ... "}
+{FCGI_PARAMS,          1, ""}
+{FCGI_STDIN,           1, "quantity=100&item=3047936"}
+{FCGI_STDIN,           1, ""}
+
+    {FCGI_STDOUT,      1, "Content-type: text/html\r\n\r\n<html>\n<head> ... "}
+    {FCGI_STDOUT,      1, ""}
+    {FCGI_END_REQUEST, 1, {0, FCGI_REQUEST_COMPLETE}}
+3. Similar to example 1, but this time the application detects an error. The application logs a message to stderr, returns a page to the client, and returns non-zero exit status to the Web server. The application chooses to send the page using more FCGI_STDOUT records:
+
+{FCGI_BEGIN_REQUEST,   1, {FCGI_RESPONDER, 0}}
+{FCGI_PARAMS,          1, "\013\002SERVER_PORT80\013\016SERVER_ADDR199.170.183.42 ... "}
+{FCGI_PARAMS,          1, ""}
+{FCGI_STDIN,           1, ""}
+
+    {FCGI_STDOUT,      1, "Content-type: text/html\r\n\r\n<ht"}
+    {FCGI_STDERR,      1, "config error: missing SI_UID\n"}
+    {FCGI_STDOUT,      1, "ml>\n<head> ... "}
+    {FCGI_STDOUT,      1, ""}
+    {FCGI_STDERR,      1, ""}
+    {FCGI_END_REQUEST, 1, {938, FCGI_REQUEST_COMPLETE}}
+4. Two instances of example 1, multiplexed onto a single connection. The first request is more difficult than the second, so the application finishes the requests out of order:
+
+{FCGI_BEGIN_REQUEST,   1, {FCGI_RESPONDER, FCGI_KEEP_CONN}}
+{FCGI_PARAMS,          1, "\013\002SERVER_PORT80\013\016SERVER_ADDR199.170.183.42 ... "}
+{FCGI_PARAMS,          1, ""}
+{FCGI_BEGIN_REQUEST,   2, {FCGI_RESPONDER, FCGI_KEEP_CONN}}
+{FCGI_PARAMS,          2, "\013\002SERVER_PORT80\013\016SERVER_ADDR199.170.183.42 ... "}
+{FCGI_STDIN,           1, ""}
+
+    {FCGI_STDOUT,      1, "Content-type: text/html\r\n\r\n"}
+
+{FCGI_PARAMS,          2, ""}
+{FCGI_STDIN,           2, ""}
+
+    {FCGI_STDOUT,      2, "Content-type: text/html\r\n\r\n<html>\n<head> ... "}
+    {FCGI_STDOUT,      2, ""}
+    {FCGI_END_REQUEST, 2, {0, FCGI_REQUEST_COMPLETE}}
+    {FCGI_STDOUT,      1, "<html>\n<head> ... "}
+    {FCGI_STDOUT,      1, ""}
+    {FCGI_END_REQUEST, 1, {0, FCGI_REQUEST_COMPLETE}}
