+		The Process class  is used to start external programs and to communicate with them.[br]
+		!WARNING AT LAST YOU HAVE TO CLOSE THE PROCESS!
+	@functions:
+		!fn: $addArg(<process-name:string>)
+		With this command you give the process name (or more arguments) for comunication.
+		Es: see the next example.

+		%process=$new(process);[br]

+		%process->$start();[br]
+		!fn: <string> $readStdout()
+		Reads the data that the process has written to standard output.
+		!fn: <string> $readStderr()
+		Reads the data that the process has written to standard error.

+		!fn: $writeToStdin(<command:string>)
+		Whit this command you send a command to the process:
+		!fn: $closekill()
+		This tries to terminate the process the nice way.[br]
+		If the process is still running after 5 seconds, it terminates the process the hard way.[br]
+		(I think that this is the better way.)[br]
+		Es:
+		%Process->close_kill();
+		!fn: $kill()
+		Kill the process in hard way.(Bad Idea)
+		!fn: $tryTerminate()
+		Tries to terminate the process.(It could be well but...)
+		!fn: $closeStdin()
+		Close the standard Input.
+		!fn: <boolean> $isRunning()
+		Return 1 if the process is running, else return 0.
+		!fn: <boolean> $normalExit()
+		Returns TRUE if the process has exited normally; otherwise returns FALSE.
+		!fn: $readyReadStdoutEvent()
+		This function is invoched by the process when there are new datas.[br]
+		The default implementation emits the [classfnc]$readyReadStdout[/classfnc]() signal.
+		!fn: $readyReadStderrEvent()
+		This function is invoched by the process when there are new error messages.[br]
+		The default implementation emits the [classfnc]$readyReadStderr[/classfnc]() signal.
+
+	@signals:
+		!sg: $readyReadStdout()
+		This signal is emitted by the default implementation of [classfnc]$readyReadStdoutEvent[/classfnc]().[br]
+		If you reimplement that function you will have to emit the signal manually (if you still need it).
+		!sg: $readyReadStderr()
+		This signal is emitted by the default implementation of [classfnc]$readyReadStderrEvent[/classfnc]().
