+# IMPORTANT: One unfortunate trait of this script is that, by necessity (for
+# now), it uses what Grype calls "directory scanning catalogers" and not "image
+# scanning catalogers" (for more information on the difference, see
+# https://github.com/anchore/syft/#default-cataloger-configuration-by-scan-type).
+# The latter is desirable here, since it equates to scanning software that is
+# determined to be installed rather than merely referenced (e.g a test
+# dependency mentioned in a lockfile). The Grype team is aware of the need to
+# make it easier to scan 'installed' software in directory scans (see
+# https://github.com/anchore/syft/issues/1039), and we can improve this script
+# when that functionality is added.
