+# This file contains help messages for missing external blobs. Each message has
+# a tag (MUST be just lower-case text, digits and hyphens) starting in column 1,
+# followed by a colon (:) to indicate its start. The message can include any
+# number of lines, including blank lines.
+#
+# When looking for a tag, Binman uses the value of 'missing-msg' for the entry,
+# the entry name or the entry type, in that order
