How to automatically generate declination Lines with TOPO!

[Bruce Tolley]

I want to combine some map and compass with a snow camping trip next month. To obviate the need to correct for declination in the field, I have been hand drawing declination lines on paper maps.

But I do own TOPO! and there must be some way to get the program to automatically generate the lines. Does anybody have a script for this or can anyone point me to a helpful website. I cannot find any help in the documentation.
