+#!/bin/bash
+# dnf-repoquery-by-srpm [dnf-options...] srpm-name...
+#
+# List the NEVRA of every package built from one of the given source RPMs
+# (given by full name as in the SOURCERPM tag, e.g., glibc-2.31-4.fc32.src.rpm).
+#
+# This script's option parser is crude and assumes that every argument that
+# doesn't begin with a dash is a source RPM name, so you must use the
+# "--opt=val" form of dnf options, not "--opt val".  Also, if you customize
+# the query format, it must not contain an embedded newline or \x01.
+#
+# Ideally "dnf repoquery" would support arbitrary query tags like rpm
+# (i.e., "rpm -qa SOURCERPM=...") and we wouldn't need this script.
