 This side project has a different take on dwm patching. It uses preprocessor directives to decide whether or not to include a patch during build time. Essentially this means that this build, for better or worse, contains both the patched _and_ the original code. The aim being that you can select which patches to include and the build will contain that code and nothing more.
 
-For example to include the alpha patch then you would only need to flip this setting from 0 to 1 in [patches.h](https://github.com/bakkeby/dwm-flexipatch/blob/master/patches.h):
