+# Generate a krb5.conf file in the current directory for testing purposes.
+# Takes one command-line argument: the default realm to use.  Strips out the
+# entire [appdefaults] section to avoid picking up any local configuration and
+# sets the default realm as indicated.
+#
+# The canonical version of this file is maintained in the rra-c-util package,
+# which can be found at <https://www.eyrie.org/~eagle/software/rra-c-util/>.
