# with mapnik 3.1.0. Note that:
#
# 1. Starting with proj version 8, this workaround will no longer be
# supported by the upstream proj project.
#
# 2. Without the workaround, mapnik configures itself without proj support.

# 3. The master branch of mapnik (after 3.1.0) appears to add native support
# for the proj 6 api, so this workaround is not likely to be needed in
# subsequent mapnik releases. At that point, this block comment and the
