Include WPKG master definition. Root element for host definitions. Define condition under which this host entry is applied. Define an environment variable to be set when the host entry applies. Define profile which should be applied to matching host. Hostname specification. It might contain regular expressions as well as well as IP-address ranges. Direct match: This is tried first always. If the hostname matches exactly the value of 'name' this host node is applied to the machine. IP-Ranges: format has to be specified as follows: start[-end].start[-end].start[-end].start[-end] examples: 192.168.1.1 192.168.1.1-254 192.168.1-5.20-50 Regular expressions: example: "test-.*" will match all machines where the hostname is starting with "test-" string. If no name attribute exists then the host entry will always match. You can omit the name attribute and use extended attribute matching like hostname (which matches the host name only, but not IP), ipaddresses, domainname etc. Main profile. You can specify the applying profile as separate "profile" nodes as well but if there is only one single profile it is recommended to use the profile-id attribute. ID referencing to the profile defined in profiles.xml
