Trac #31177: Add graphviz, pygraphviz packages

Release Manager · Release Manager · commit ca1e4a13a4ed · 2021-03-07T12:07:05.000+01:00
Several places in Sage refer to graphviz. When building from source, graphviz can make use of various optional dependencies: https://graphviz.org/download/source/ It seems too tricky to make it a normal package. Current versions of `graphviz` seem to be licensed under the Eclipse Public License 1.0, which is a free software license but GPL- incompatible. https://gitlab.com/graphviz/graphviz/-/blob/master/LICENSE So probably we should not make it a standard package. Thus, we add it as a dummy script package only, so that we can provide system package information (https://repology.org/project/graphviz/versions). We also add `pygraphviz` as a pip package - as part of Meta-ticket #31176 (Add packages from 3-manifolds / computop) URL: https://trac.sagemath.org/31177 Reported by: mkoeppe Ticket author(s): Matthias Koeppe Reviewer(s): David Coudert
