> The RobotsRulesParser command-line tool, used to check a list of URLs against one robots.txt file, should use the value of the property {{http.robots.agents}} as fall-back if no user agent names are explicitly given as command-line argument. In this case it should behave same as the robots.txt parser, looking first for {{http.agent.name}}, then for other names listed in {{http.robots.agents}}, finally picking the rules for {{User-agent: *}}
> {noformat}
> $> cat robots.txt
> User-agent: Nutch
> Allow: /
> User-agent: *
> Disallow: /
> $> bin/nutch org.apache.nutch.protocol.RobotRulesParser \
>       -Dhttp.agent.name=mybot \
>       -Dhttp.robots.agents='nutch,goodbot' \
>       robots.txt urls.txt 
> Testing robots.txt for agent names: mybot,nutch,goodbot
> not allowed:    https://www.example.com/
> {noformat}
> The log message "Testing ... for ...: mybot,nutch,goodbot" is misleading. Only the name "mybot" is actually checked.
