Grabbing all nn messages on the same subject

Want to read every current posting with 'Irangate' in the subject line?
At your  prompt, enter:

       nngrab iran 

Go read three of Keats' odes, because this routine takes a while.  It searches 
all posts in all news groups.  It gathers the messages that match into one 
group and uses menus just as nn does.  In fact, you will be in nn when
you read the matching messages and can use all nn commands to act on them.

The command matches regardless of case unless you choose

      nngrab -c Iran
