emacs-team needs you 👉 to properly test your packages

[Liliana Marie Prikler]

Hi Guix,

I just pushed a patch that flips the switch on emacs-build-system,
making it actually run tests by default.  There is a manifest to build
all emacs packages now; attached is a variant that allows you to skip
some builds that you know to fail.

It will take some time to get all packages to build properly, and I
will be working on this slowly over the next few days (hopefully not
weeks).  If you'd like to contribute, take some time and a portion of
the packages (e.g. the ones you have in your own manifest) and ensure
that they build.  Submit any patches that you need to

=> 76...@debbugs.gnu.org <=

or open a new issue and block 76686 by it.  Don't forget to tag your
patch as emacs-team and CC us :)

Cheers
