+# FIXME Remove hack for polymorphic versions
+# This package uses a ugly hack to be able to dispatch, given the same
+# version, to different binary packages based on the platform that is
+# running spack. See #13827 for context.
+# If you need to add a new version, please be aware that:
+#  - versions in the following dict are automatically added to the package
+#  - version tuple must be in the form (checksum, url)
+#  - checksum must be sha256
+#  - package key must be in the form '{os}-{arch}' where 'os' is in the
+#    format returned by platform.system() and 'arch' by platform.machine()
