working with port options from commandline

[Volodymyr Kostyrko]

Hi all.

I'm all about automation. I'd like to automate most tasks so I can 
schedule them or write a script with which everything would be done 
automatically.

I have some difficulties with current port options framework:

1. Is there a good way to set/unset any option from command line without 
firing up dialog? Something like 'make -C port/dir -DSET=OPT1,OPT2 
-DUNSET=OPT3 updateconfig'.

2. Is there a good way to query for option updates? You know when you 
are building a port the option dialog will still be shown if there are 
new options not present in current config. Can I get those options 
somehow like 'make -C port/dir changedconfig'?

I think I need to write some scripts to handle this situations myself 
but I just want to ask whether someone had done that before or maybe 
such functionality is pending?
