 ciao,

 frescobaldi @3.1.3 and frescobaldi-devel @20201226 fail to build with
 following error:

 {{{
 error: Multiple top-level packages discovered in a flat-layout: ['i18n',
 'linux', 'macosx', 'windows', 'frescobaldi_app'].

 To avoid accidental inclusion of unwanted files or directories,
 setuptools will not proceed with this build.

 If you are trying to create a single distribution with multiple packages
 on purpose, you should not rely on automatic discovery.
 Instead, consider the following options:

 1. set up custom discovery (`find` directive with `include` or `exclude`)
 2. use a `src-layout`
 3. explicitly set `py_modules` or `packages` with a list of names

 To find more information, look for "package discovery" on setuptools docs.

 3.1.3-20201226 -s /opt/mp/bin/frescobaldi
 Exit code: 1
 }}}

 main.log output attached.
