+Depending on how the script is called we change its behavior.
+For backwards compatibility, moving or symlinking the script to a
+file name starting with \fileent{mkluatexfontdb} will cause it to
+trigger a database update on every run.
+Running as \fileent{fontdbutil} -- the new name -- will do this upon
+request only.
+
+There are two naming conventions followed here: firstly that of
+utilities such as \fileent{mktexpk}, \fileent{mktexlsr} and the likes,
+and secondly that of \fileent{fmtutil}.
+After support for querying the database was added, the latter appeared
+to be the more appropriate.
