+
+/*!
+ It can split the mplayer status line into lines.
+ It also provides some Qt 3 like functions like addArgument().
+
+ There are two working modes, controlled by the USE_TEMP_FILE define.
+ If USE_TEMP_FILE is 1 it will send the output of mplayer to a temporary
+ file, and then it will be read from it. Otherwise it will read from
+ standard ouput as usual.
