The main goal of this investigation is to organize shared data and code across 
multiple binary files. This is especially important for something like a base
layer that will be used in a program that supports hot-reloading or plugins.

Each isolated example in this repository explores a way to set up the base
layer, plugin, and main program.

The examples:

*_concrete - Concrete examples for each operating system I have investigated
             showing how to setup and use various types of dynamic linking. In
             these the "base" layer goes through load-time linking, the
             "plugin" layer goes through run-time linking, and the "main" layer
              acts as the executable that must bind it all together.

xlist - My prefered solution to the problem posed in the investigation which
        relies only on run-time linking. It uses an xlist to manage the
        maintenance burden of run-time linking, and a basic outline of the
        abstracted form of each layer.
