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
