DOCUMENTATION:

    See  pymontrace -h  and  https://cakemanny.com/pymontrace  or
    docs/SUMMARY.md in the github repository for some initial documentation.


WARNING:

  - This is under early development and is in no way safe to use against
    production workloads.

  - The interface will change wildly without warning. There are no versioning
    guarantees at this point.


CAVEATS:

  - Use on macOS requires root. Use `sudo`.

  - Probes will only fire if the function is entered after the probe has
    been installed. This means that top level statements cannot be traced and
    that the statements inside an outermost forever-loop cannot be traced.
