+# Some selections are used multiple times throughout the module.
+# We define their builders upfront here. These builders are local
+# and follow the PEP 8 Style Guide for Python Code
+# https://www.python.org/dev/peps/pep-0008/#descriptive-naming-styles
+# > _single_leading_underscore: weak "internal use" indicator.
+# E.g. from M import * does not import objects whose names
+# start with an underscore.
+#
+# The cut values are set in the body of the builders,
+# such that they are immutable.
+# This ensures that:
+# - Only one filter or combiner instance is created and called.
+# This speeds up the selection.
+# - Cut values are set only once and cannot be overwritten.
+# The code is easier to read and less error-prone.
+#
+# Some builders are standalone and not part of the "configuration-flow"
+# mentioned in the style-guidelines used for Moore/RecoConf:
+# https://lhcbdoc.web.cern.ch/lhcbdoc/moore/master/recoconf/recoconf.html
+# The idea behind this is to re-define basic particles as starting point
+# for selections in the module. These builders use proto-particle-makers
+# and pvs directly in the body of the function. Other common selections,
+# like the Xi- builders consume "rare" input particles.
+# These rare input particles are intended to be used to configure the
+# control flow and speed up selections.
