-# vk_layer_documentation_generate.py overview
-# This script is intended to generate documentation based on vulkan layers
-# It parses known validation layer headers for details of the validation checks
-# It parses validation layer source files for specific code where checks are implemented
-# structs in a human-readable txt format, as well as utility functions
-# to print enum values as strings
-
-# NOTE : Initially the script is performing validation of a hand-written document
-# Right now it does 3 checks:
-# 1. Verify ENUM codes declared in source are documented
-# 2. Verify ENUM codes in document are declared in source
-# 3. Verify API function names in document are in the actual API header (vulkan.py)
-# Currently script will flag errors in all of these cases
-
-# TODO : Need a formal specification of the syntax for doc generation
-# Initially, these are the basics:
-# 1. Validation checks have unique ENUM values defined in validation layer header
-# 2. ENUM includes comments for 1-line overview of check and more detailed description
-# 3. Actual code implementing checks includes ENUM value in callback
-# 4. Code to test checks should include reference to ENUM
-
-
-# TODO : Need list of known validation layers to use as default input
-# Just a couple of flat lists right now, but may need to make this input file
-# or at least a more dynamic data structure
