                    <div><span>Hi - the attached patch provides implementations and tests for sys::fs::can_read() and sys::fs::can_write() for Unix.  These were adapted from the previous implementations in lib/Support/Unix/Path.inc.  can_execute() could be implemented quite similarly, but I wasn't sure where the best place to add a test for it would be, so left it out for now.</span><span></span></div><div><span><br></span></div><div><span>Thanks,</span></div><div><span>Liam</span></div>
