The build system has a number of scripts that automate addition/removal/change
of executability of files. But it is uncertain which scripts (or make commands)
have to be run after which operation, which might make users run time-consuming
clean builds.
Documentation should be written on ways of making the build system take into
account the following actions in the most practical manner: adding a file,
removing a file, adding/removing "main" functions from files and other
operations (if any)
