Doug,

1)  I wonder if I could use mergemaster to compare 2 directories and 
merge differencies as neccessary.  To explain: I have all config files I 
touch saved with full path somewhere in /root.  And therefore I'd like 
mergemaster or some other tool to compare all files in my backup 
directory with newly installed (config) files.

2)  I have a file with list of ports I usually install and I created 
script that try to install them.  This is quite useful after `pkg_delete 
-a`.  Now I can do it with `portupgrade -iN $plist` but I haven't 
figured how I can make portmaster to do the same.

Any suggestions please ?

Thank you,

Martin
