description         A library of Fortran modules and routines for scientific calculations
long_description    This is a unitary collection of Fortran modules and procedures \
                    for scientific calculations. The library aims to provide a simple \
                    and generic environment for any scientific or mathematic computations. \
                    The project is largely inspired by SciPy for Python \
                    and tries to closely follow its guidelines and naming convention.

# cmake.generator     Ninja
# Avoid Ninja for now due to:
# https://github.com/QcmPlab/SciFortran/issues/1
# The issue seems to affect only non-MPICH build,
# but we rather use a safer option for both.
