This repo was born out of deep frustration in trying to understand
precisely how linkers work. The project contains folders,
each of which explores a *single* idea in the working
of the linker.

[Reference on symbol resolution](https://www.airs.com/blog/archives/49) is the only place
I've ever seen this documented.

executable, as well as why the linker is order sensitive.
