+for tabular appearance in those environments if possible.
+
+If I<escape_function> is set then the array members are processed by this
+function before being returned.
+
+I<format_function> overrides the normal HTML or LaTeX function for returning
+formatted CDRs. It can be set to a subroutine which returns an empty list
+to skip usage detail:
