NBIS is pretty complicated to update, seeing as we've made quite a few changes to get it to compile as a library. With those scripts, we can easily trim headers to remove functions we don't use, rename global variables, and do any sort of fixups that are necessary right now. In the future, removing unused NBIS functions might be as easy as updating that script, re-running it, and pushing the changes. Note that remove-function.lua is a very crude parser that only supports NBIS' style of declaration, with the return type on the same line as the function name. I wouldn't recommend trying to use it in another project. Callcatcher (https://github.com/caolanm/callcatcher) was also used to remove additional unused functions.
