+# Wrapper of clang-tidy
+
+# Use case #1: by RBE input processor to get resource dir.
+# Command:
+# clang-tidy.sh --version -- -print-resource-dir
+# Outputs:
+# same as clang-tidy --version -- -print-resource-dir
+
+# Use case #2: by soong generated ninja build rules.
+# Calls clang-tidy and touch output .tidy file.
+# Calls clang or clang++ to generate .tidy.d file.
+# Environment:
+# CLANG_CMD: 'clang' or 'clang++'
+# TIDY_FILE: path to output .tidy file
+# TIDY_TIMEOUT: optional for clang-tidy
+# Arguments: # same as clang-tidy
+# <in-file-path> (required, input file)
+# <clang-tidy flags> (optional)
+# "--" (required to separate arguments)
+# <clang/clang++ flags> (optional)
+# Outputs:
+# .../*.tidy (the output file)
+# .../*.tidy.d (the dependent file is output file plus .d suffix)
+# stdout and stderr from clang-tidy
+# stdout and stderr from clang/clang++ if clang-tidy succeeds
