-# If more than one rule matches a given file, the latest rule is used.
-# The file should be generally kept sorted, except when it is necessary
-# to use a different order due to the fact above. In that case, use
-# '# sort-order-reset' comment line to reset the sort order.
-#
-# Recipes for a few common cases:
-#
-# 1. Specific directory with all its contents:
-#
-#    /components/app_trace/
-#
-#    Note the trailing slash!
-#
-# 2. File with certain extension in any subdirectory of a certain directory:
-#
-#    /examples/**/*.py
-#
-#    This includes an *.py files in /examples/ directory as well.
-#
-# 3. Contents of a directory with a certain name, anywhere in the tree:
-#
-#    test_*_host/
-#
-#    Will match everything under components/efuse/test_efuse_host/,
-#    components/heap/test_multi_heap_host/, components/lwip/test_afl_host/, etc.
-#
-# 4. Same as above, except limited to a specific place in the tree:
-#
-#    /components/esp32*/
-#
-#    Matches everything under /components/esp32, /components/esp32s2, etc.
-#    Doesn't match /tools/some-test/components/esp32s5.
-#
-# 5. Specific file:
-#
-#    /tools/tools.json
-#
-# 6. File with a certain name anywhere in the tree
