Christian Lademann's contribution: new capabilities in smb.conf.
'<' and '|' characters indicate read file and execute command respectively, and feed the output into the parameter (!!!). '<$' and '|$' means run standard_sub_basic() on them. this is going to be fun to document in smb.conf.5.... also, Christian created a new "online" service parameter. services can be taken "off-line".... (This used to be commit 15f44d28916cdc1432bffdbb999c7cf7efd8fb86)
