# NOTE: most generic tasks (static-analysis, format, lint, unit, snapshot, release,
# changelog, ci-release, etc.) are now provided natively by anchore/go-make and
# defined in .make/main.go. This file holds the syft-specific tasks that go-make
# wraps via `wrap("<name>")` calls — keep descriptions (`desc:`) populated so they
# show up in `make help`.
