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