%global _description \
Cython wrapper to provide python interfaces to Proj. \
Performs cartographic transformations between geographic (Lat/Lon) \
and map projection (x/y) coordinates. Can also transform directly \
from one map projection coordinate system to another. \
Coordinates can be given as numpy arrays, python arrays, lists or scalars. \
Optimized for numpy arrays.

# some notes on the test suite:
# total number of testcases for version 3.4.1 is 841.
# -m "not network"            ==> deselects 24 tests
# -m "not grid"               ==> deselects 11 tests
# --ignore=test/test_utils.py ==> deselects 14 tests
#
# network: these tests depend on downloading data from the network
# which is not possible during the build process.
#
# grid:  1 failure for epel9 (test/test_transformer.py)
# note on failing grid test:
# this seems caused by an intentional change of behavior of the proj library.
# between proj v9.0.1 and proj v9.1.0
# The test suite of pyproj has adapted to the new behaviour but
# it was forgotten to add compatibility code to allow use of the
# older proj versions as well.
# Therefore it seems safe to just skip this test for now.
# See: https://github.com/pyproj4/pyproj/issues/1141
#
# test/test_utils.py
# this module imports pandas and xarray and cannot be used
# as long as those python modules are not packages for epel9
