Any `.lua`` files in that directory get loaded as one of the last parts of pulling things into the runtime. So, pretty much everything else should be loaded.
My thinking is to make it easier to break out parts of my config into the individual files and to make it easier to add little scripts to mod behavior.
For example, putting this script in the directory configures Neovim to print "File saved!" every time a file is written
So far. So good. I've created a half dozen files and everything is working as expected.
