halreport is a command-line utility that generates a report about HAL connections for a running LinuxCNC (or other HAL) application. The report shows all signal connections and flags potential problems. Information included:

1. System description and kernel version.
2. Signals and all connected output, io, and input pins.
3. Each pin’s component_function, thread, and addf-order.
4. Non-realtime component pins having non-ordered functions.
5. Identification of unknown functions for unhandled components.
6. Signals with no output.
7. Signals with no inputs.
8. Functions with no addf.
9. Warning tags for components marked as deprecated/obsolete in docs.
10. Real names for pins that use alias names.

The report can be generated from the command line and directed to an output file (or stdout if no outfilename is specified).
