And the doco is just as deficient as ever because:

1) there is a 4th trigger called %triggerprein

2) triggers are fired by provides, not package names

3) previously (like >5y ago) only a single trigger was run
when multiple trigger relations between 2 packages existed;
all triggers are now run.

4) triggers on directory/file paths (and even globs) are implemented
