.Sh USER-DEFINED FORMAT
If you want to generate configuration not for routers, but for some
other programs/systems, you may use user-defined formatting, like in
example below:

Recognized format characters: %n - network, %l - mask length,
%N - object name, %m - object mask and %i - inversed mask.
Recognized escape characters: \\n - new line, \\t - tabulation.
Please note that no new lines inserted automatically after each sentence,
you have to add them into format string manually, elsewhere output will
be in one line (sometimes it makes sense):
