Group File

Group file contains declarations of groups containing users and other groups, 
with possibly an IP address template. 
Group declarations as viewed from top-level look like this: 

        groupname: item, item, item

The list of items is called a group definition. 
Each item can be a username, an already-defined groupname, or a
comma-separated list of user and group names in parentheses. 
Any of these can be followed by an at sign @ followed by either
a single IP address template, or a comma-separated list of IP address templates 
in parentheses. The following are valid group declarations: 

        authors: john, james
        trusted: authors, jim
        cern_people: @128.141.*.*
        hackers: marca@141.142.*.*, sanders@153.39.*.*,
                 (luotonen, timbl, hallam)@128.141.*.*,
        cern_hackers: hackers@128.141.*.*
