Modules are Website Publisher’s programming interface to customizing or extending its existing functionality without modifying the core code. This allows the behaviour of Website Publisher to be altered or improved in ways that, when compared to modifying the core PHP code, are both more organized and more likely to survive through updates to Website Publisher itself.
A first draft of documentation on the Website Publisher Module Framework is available on the Interspire Developer Network, here:
