      L3BUILD MANIFEST SETUP
      ======================
      This file contains all of the code that is easily replaceable by the user.
      Either create a copy of this file, rename, and include alongside your `build.lua`
      script and load it with `dofile()`, or simply copy/paste the definitions below
      into your `build.lua` script directly.

      Setup of manifest "groups"
      --------------------------

      The grouping of manifest files is broken into three subheadings:

      * The development repository
      * The TDS structure from `ctan`
      * The CTAN structure from `ctan`

      The latter two will only be produced if the `manifest` target is run *after*
      the `ctan` target. Contrarily, if you run `clean` before `manifest` then
      only the first grouping will be printed.

      If you want to omit the files in the development repository, essentially
      producing a minimalist manifest with only the files included for distribution,
      make a copy of the `manifest_setup` function and delete the groups under
      the ‘Repository manifest’ subheading below.
