ExplorerPatcher has a simple, built-in mechanism that allows users to load their own DLL into explorer.exe right after ExplorerPatcher finishes initializing its hooks. Interested users should place a DLL called ep_extra.dll in C:\Windows. When ExplorerPatcher finishes its setup, it loads the ep_extra.dll library and calls the ep_extra_EntryPoint function. Although this is very useful so that users can load their custom code, it is quite limited at the moment, as it loads just one DLL.

This project is a solution to this issue. A chainloader is implemented here, that looks for other modules matching the ep_extra_*.dll pattern in C:\Windows as well, and loads them one after the other.
