fetchmail syntax question

[Jude DaShiell]

How do you use the plugin option and where is it used in a .fet chmailrc 
file?  I want to have ssh do the connecting for my e-mail downloads but 
what was written on the fetchmaill man page for the syntax wasn't very 
helpful.  From what I did take away from that, maybe something like: 
plugin ssh e-mail address, password <cr> might work but why put %h %p in 
that language unless those were supposed to illustrate place-holder 
variables?
