The updates here are generated via a daily Github Workflow from https://github.com/openSUSE/autoupdate-perl .
To generate the spec https://github.com/openSUSE/cpanspec is used.

Then someone has to manually go over the updates and create submit reqests to devel:languages:perl (currently usually done by @tinita).
That last step is currently not automated because too many modules need manual handling (fixing license, dependencies, description etc.)

If you see a failing module, you can branch it from here and try to fix it.
