[forge-users] Need explanation for forge addon folder structure

[forge-users at lists.jboss.org]

Hello Mani, 

Here is an explanation of each module and their relationship: 

* addon: The addon project. This module should depend on api (and spi if available) in compile time and impl in runtime. The artifact produced by this project should be a JAR with the classifier forge-addon
* api: any artifact that is supposed to be exposed by your addon. 
* impl: this is where the implementation of your API lies and they should never be accessed externally. 
* spi (when feasible): Use a SPI when you want other addons to provide extensions for your addon.
* tests: This is where the integration tests are kept.
