+### Modes
+
+- Use `poll` to run the script wait for it to exit. On exit, the label is updated to show everything the script wrote to `stdout`.
+- Use `watch` to start a long-running script. Every time the script writes to `stdout`, the label is updated to show the latest line.
+    Note this does not work for all programs as they may use block-buffering instead of line-buffering when they detect output being piped.
