4wciia - Whose Code Is It Anyway
5
6Determines code owner of the file/folder relative to the llvm source root.
7Code owner is determined from the content of the CODE_OWNERS.TXT
8by parsing the D: field

10usage:
11
12utils/wciia.py  path
13
14limitations:
15- must be run from llvm source root
16- very simplistic algorithm
17- only handles * as a wildcard
18- not very user friendly
19- does not handle the proposed F: field
