# Include the specified classes
Puppet::Parser::Functions::newfunction(:include, :arity => -2, :doc =>
"Declares one or more classes, causing the resources in them to be
evaluated and added to the catalog. Accepts a class name, an array of class
names, or a comma-separated list of class names.
The `include` function can be used multiple times on the same class and will
only declare a given class once. If a class declared with `include` has any
parameters, Puppet will automatically look up values for them in Hiera, using
`<class name>::<parameter name>` as the lookup key.
Contrast this behavior with resource-like class declarations
(`class {'name': parameter => 'value',}`), which must be used in only one place
per class and can directly set parameters. You should avoid using both `include`
and resource-like declarations with the same class.
The `include` function does not cause classes to be contained in the class
where they are declared. For that, see the `contain` function. It also
does not create a dependency relationship between the declared class and the
surrounding class; for that, see the `require` function.") do |vals|
