+# Updating these to the latest version all the time is OK and a good idea.

+# here should also be compatible with the pinned versions in bob-devel. For most
+# dependencies, you want to put the exact version of bob-devel in here as well. It is
+# best to keep this in sync with:
+# https://github.com/AnacondaRecipes/aggregate/blob/master/conda_build_config.yaml The
+# names here should not contain dots or dashes. You should replace dots and dashes with
+# underlines.
