General just usages

# list all "just" available recipes
$ just
# list commands that would run by RECIPE
$ just -n/--dry-run RECIPE

# (just recipes `check` and `save` both use `l3build_wrapper.py`)
# print help text of `l3build_wrapper.py`
$ just [check|save] -h
# check/save one or more tests and/or testsuites
$ just check zutil tblr
$ just save zutil-001 tblr-loading

Note: As configured by .justfile in this repository, just invoked from any subdirectories acts the same as being invoked from the top-level directory.
