yutsing [1] filed a deletion request for jupyter-wolframengine_kernel [2]: This package is not appropriate, since the jupyter kernel for wolframengine is installed to user directory hence no need to be managed by system package manager. The structure of this package also brings inconvenience. I apologize for submitting this package when I is not so familiar with the project and aur, and I decide that this mistake should be resolved.
