# General principle of categorization:
|
||||
#
|
||||
# - Each category, in general, denotes a module or feature.
|
||||
#
|
||||
# - We assign each allocation to the module/feature that directly
|
||||
# caused the allocation irrespective of which higher level module
|
||||
# caused the allocation. There are very few exceptions usually when
|
||||
# an allocation belongs both to a feature-category and to a
|
||||
# module-category.
