+wciia - Whose Code Is It Anyway
+
+Determines code owner of the file/folder relative to the llvm source root.
+Code owner is determined from the content of the CODE_OWNERS.TXT
+by parsing the D: field
+
+usage:
+
+utils/wciia.py path
+
+limitations:
+- must be run from llvm source root
+- very simplistic algorithm
+- only handles * as a wildcard
+- not very user friendly
+- does not handle the proposed F: field
