Why we should include this into the repository, i.e. what does it do that the alternatives do not? Yes, there are alternatives in Solus, as Texlive and Latexila, but Kile is the best. I use latex for my daily research and Kile is the only one full e complete of resources. There is a lack of maintenance for Latexila, is incomplete.
