Shared spool directory

If you want to share single spool directory with multiple grouped Unix users, then you can setgid it and assure that umask is group friendly. For convenience you can set umask globally for invoked NNCP commands in the configuration file. For example:

$ chgrp nncp /usr/local/etc/nncp.hjson /var/spool/nncp
$ chmod g+r /usr/local/etc/nncp.hjson
$ chmod g+rwxs /var/spool/nncp
$ echo 'umask: "007"' >> /usr/local/etc/nncp.hjson
