+=head1 DESCRIPTION
+
+The B<copyauth> command copies existing AFS credentials in the local
+cell to the foreign cell specified on the command line.
+
+The functionality in this command is largely superseded by L<aklog(1)>.
+
+=head1 CAUTIONS
+
+This functionality only works if you have a shared AFS key across multiple
+cells, which is strongly discouraged as it weakens security. If you do
+not understand those risks, you should not use this tool.
