+# Tests for the command line option '--version', which outputs the version
+# number of make.  NetBSD's make does not have a version number, but the bmake
+# distribution created from it has.
+
+# As of 2021-12-23, the output is a single empty line since the '--' does not
+# end the command line options.  Command line parsing then continues as if
+# nothing had happened, and the '-version' is split into '-v ersion', which is
+# interpreted as "print the expanded variable named 'ersion'".
