You can use include function if:
class is not parameterized.
class is parameterized, but provide default values: (i.e. class sample
($param = 'val1') {...})
class is already declared (you can include class multiple times
throughout your manifests).
include does not support:
stages
relationship (require function provides include+require.)
class declaration supports:
classes that are both parametrized and non-parametrized.
stages
relationship
class declaration does not support:
redeclaration of classes
I think that's all. HTH,
