The idea is to set and export PAN_HOME before you start pan.  If pan sees 
that variable set, it tries to look in that location for its config, 
instead of in the default ~/.pan2.  

By creating, setting the executable bit on, and then using a starter 
script, say pan.seldom , with a couple lines in it setting and exporting 
PAN_HOME like this:

export PAN_HOME="/home/beartooth/.pan.seldom"

exec pan

... you can then run that script and start pan with a separate set of 
data files, the ones in ~/.pan.seldom instead of the normal ones in 
~/.pan2 .

Then you can run pan normally in your normal instance, and when you want 
to, you can run pan.seldom , and it'll start the second instance, using 
the files in the new location.  If it's done correctly, each instance 
"just works" and doesn't overwrite anything in the other data file 
location.

The one catch is that you either have to setup everything new for the 
second location, or if you start by copying files from the old location 
(.pan2), you have to do a search in all the copied files for every 
existence of the old path (.pan2) and change it to the new path 
(.pan.seldom).  This is because the paths are stored in a couple of the 
files and if you don't change them, they'll still point to the ones in 
the old location.

Does that ring any bells yet?  I'm almost sure we went thru that once 
before, but at least the first time it you said it was too complex still, 
so I created a step-by-step for you, but maybe you didn't try it.
