description         Software for building and coupling weather, climate, and related models
long_description    ESMF defines an architecture for composing complex, coupled \
                    modeling systems and includes data structures \
                    and utilities for developing individual models.

# Fix builds for 10.6-10.8.
# Was fixed upstream after ESMF version 8.8.1.
# Remove this patch on next release after 8.8.1.
# Fixes unknown 'task_info_data_t', 'TASK_VM_INFO_COUNT', 'TASK_VM_INFO'.
# Patch copied from upstream patch by @barracuda156.

# Fix builds for 10.6.
# Upstream fix after ESMF version 8.8.1 is pending.
# Remove this patch on next release after 8.8.1.
# Fixes "error: missing terminating ' character".
# This is actually a preprocessor bug that breaks only in
# Clang 11 and other early Clang versions.
