"""
This script is used in GitHub Actions to determine what docs/boards are
built based on what files were changed. The base commit varies depending
on the event that triggered run. Pull request runs will compare to the
base branch while pushes will compare to the current ref. We override this
for the adafruit/circuitpython repo so we build all docs/boards for pushes.
When making changes to the script it is useful to manually test it.
You can for instance run
```shell
tools/ci_set_matrix ports/raspberrypi/common-hal/socket/SSLSocket.c
```
and (at the time this comment was written) get a series of messages indicating
that only the single board raspberry_pi_pico_w would be built.
