Instruction RENDER
The RENDER instruction renders a file from a template, and writes it to the
specified destination. It accepts the same key=value arguments as
INCLUDE. These arguments are made available in the template.
Example:
RENDER widgetfactory.tmpl /etc/widgetd/server.conf host="example.org" port=1234
The short form name (meaning name=name) is also supported here.
For example, in a component where host and port are available in the
environment:
RENDER widgetfactory.tmpl /etc/widgetd/server.conf host port
