## git-rank-contributors: a simple script to trace through the logs and
|
||
|
|
## rank contributors by the total size of the diffs they're responsible for.
|
||
|
|
## A change counts twice as much as a plain addition or deletion.
|
||
|
|
##
|
||
|
|
## Output may or may not be suitable for inclusion in a CREDITS file.
|
||
|
|
## Probably not without some editing, because people often commit from more
|
||
|
|
## than one address.
