MarsSeed [1] filed a deletion request for python2-fluidsim-hg [2]: I suggest to delete this legacy Python 2 based package, since the source code supports Python 3 and this Python 2 based one is heavily broken on AUR because of so many missing dependencies. Maintainer @jadelord expressed that they no longer use Arch Linux so it is not possible for them to take an active role in the upkeep of this package. Many core scientific Python modules have deliberately moved on from Python 2 to support Python 3 exclusively during the last 3 years; therefore legacy Python 2 scientific library package maintenance is best be avoided, or otherwise would be a significant effort. (Maybe pip/PyPI or Conda/Conda-Forge could be a working option for those people who might need such deprecated versions.) Safe to delete from here, nothing depends on this package on AUR.
