+/**
+* System offers cross platform compatible system functions
+*
+* Static functions for different operations. Should work under
+* Unix and Windows. The names and usage has been taken from its respectively
+* GNU commands. The functions will return (bool) false on error and will
+* trigger the error with the PHP trigger_error() function (you can silence
+* the error by prefixing a '@' sign after the function call, but this
+* is not recommended practice.  Instead use an error handler with
+* {@link set_error_handler()}).
+*
+* Documentation on this class you can find in:
+* http://pear.php.net/manual/
+*
+* Example usage:
+* if (!@System::rm('-r file1 dir1')) {
+*    print "could not delete file1 or dir1";
+* }
+*
+* In case you need to to pass file names with spaces,
+* pass the params as an array:
+*
+* System::rm(array('-r', $file1, $dir1));
