This script was created to find all open PRs that have merge
|
|
conflicts and then add a the 'status: merge conflict' label to any PR
|
|
which does not already have the label.
|
|
|
|
To run the script for a specific language, call the script with the language
|
|
name as the first argument.
|
|
|
|
Note: It is possible that it could take more than 4 seconds for GitHub to
|
|
determine if a PR is mergeable. If that happens, the PR will not be labeled.
