+= Fonction du module =
+
+This module allows to enable technical logging into Dolibarr. Logging is used to save messages into log files :
+
+* Into a file
+** File will be by default '''DOL_DATA_ROOT/dolibarr.log''' (for example '''C:/dolibarr/documents/dolibarr.log''').
+** You can change file name on the setup page of module.
+* Into systems logs (using syslog)
+
+See module setup to choose.
+
+= PHP functions =
+
+== Definition ==
+
+To use loggin in your PHP coding, you must use the following function :
+
+<source lang="php">
+dol_syslog($message, $level = LOG_INFO)
+</source>
+
+''This function is defined into file dolibarr/htdocs/lib/functions.lib.php''
+
+== Parameters ==
+
+* '''$message''' : string with message to write into log file
+* '''$level''' : constant that define level of message. It can have following values:
+** On Windows server: LOG_ERR=4, LOG_WARNING=5, LOG_NOTICE=LOG_INFO=LOG_DEBUG=6
+** On Unix/Linux server : LOG_ERR=3, LOG_WARNING=4, LOG_INFO=6, LOG_DEBUG=7
+** You can then set the level of messages you want to write, with the module setup page.
+= Notes =
+''"Syslog functions are bugged with Windows et generates memory protection fault.''
+''To solve this, use the file logging instead of syslog logging (see module setup page).
+If SYSLOG_FILE_NO_ERROR is defined in your PHP code, no message will be output on screen when there is an error when writing the log message."''
