define service{
host_name srv-web
service_description Http
service_dependencies srv-db,mysql
}

Can a service have more than one dependency? If so, how is it defined.

Wiki says:
You can create several dependencies for a given service, but you must add a separate service dependency definition for each dependency you create.
Is the following definition for when applying more than one dependency?

define servicedependency{
host_name Host B
service_description Service D
dependent_host_name Host C
dependent_service_description Service F
execution_failure_criteria o
notification_failure_criteria w,u
}

Thank you for clearing this up. I will update the wiki if necessary.
