I am building openSUSE packages for lml & moban at https://build.opensuse.org/project/show/home:jayvdb:soe , and noticed that the tests and docs/source are missing, so there is only one doctest running to validate the package.
If they are not too big, it would be good to include tests and docs/source in the source tarball.
Alternatively, a second tarball including those could be created during the release process, to be used by packagers.
(I expect I will encounter the same problem when polishing the package for moban)
