michael@0	1	# Categorization rules for spacetrace
michael@0	2	#
michael@0	3	# This file defines the stack frame rules that will categorize
michael@0	4	# allocations that spacetrace processes. The format of this file is
michael@0	5	#
michael@0	6	# <categoryname>
michael@0	7	# initial string match for stack frame n
michael@0	8	# initial string match for stack frame n+1
michael@0	9	# initial string match for stack frame n+2
michael@0	10	#
michael@0	11	# The key in the matching rule is that for every rule, we provide a
michael@0	12	# snippet of the stack frame - contiguous substring matches.
michael@0	13	# categorynames and rules substring matches are case sensitive
michael@0	14	#
michael@0	15	# Predefined Categories
michael@0	16	# "All" - All allocations [default]
michael@0	17	# "uncategorized" - All allocations that don't match any category
michael@0	18	#

michael@0	24	# General principle of categorization:
michael@0	25	#
michael@0	26	# - Each category, in general, denotes a module or feature.
michael@0	27	#
michael@0	28	# - We assign each allocation to the module/feature that directly
michael@0	29	# caused the allocation irrespective of which higher level module
michael@0	30	# caused the allocation. There are very few exceptions usually when
michael@0	31	# an allocation belongs both to a feature-category and to a
michael@0	32	# module-category.
