-/**
-* 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));
