sub main() {
	return $node->isAgent;
}

This script works and solves the problem.

However, I can not find proper documentation for $node object and its attributes / methods.
I need to write different script for my different template which will check if $node - platform name, contains string "windows" then to automatically apply different template.

Please help me with simple if expression, contains (or RegExp) and how to get platform name from $node object ?

Thank you
