There's a certain class-naming convention that has developed over time within the Puppet community, and it's really worth taking these into account when structuring your classes:
- init.pp: init.pp contains the class named the same as the module, and is the main entry point for the module.
- params.pp: The params.pp pattern (more on this later in the chapter) is an elegant little hack, taking advantage of Puppet's class inheritance behavior. Any of the other classes in the module inherit from the params class, so have their parameters set appropriately.
- install.pp: The resources related to installing the software should be placed in an install class. The install class must be named <modulename>::install ...
