+- Update to new upstream release 20130422
+* --ctrlc will send SIGINT to tasks running on remote computers and
+  thus killing them.
+* --load now uses `ps` to see immediately see the number of running
+  processes instead of `uptime` thus making --load react much faster.
+*  --retries works with --onall.
+* --nice works under tcsh.
+- Ship license file and do tarball signature verification
