This function makes it possible to build an Emacs instance that, instead of launching an Emacs built by Nix, configures an Emacs already present on the system to use the packages built by Nix. This **requires** that the versions of the two Emacsen (i.e. the one used by Nix to build and the one used to run the packages) are kept in sync, otherwise byte-code incompatibilities may lead to undefined behaviour.
