 This is a fork of [golines](https://github.com/segmentio/golines) to be usable as a library.
 
+I considered other options before deciding to fork, but there are no straightforward or non-invasive changes.
+
+Simply isolating some code within a package will not address the root issue unless the code is converted to a dedicated module and all debug/graph-related code is removed.
+Realistically, this is not possible.
+
+Issues should be open either on the original [golines repository](https://github.com/segmentio/golines) or on [golangci-lint repository](https://github.com/golangci/golangci-lint).
+
+**No modifications will be accepted other than the synchronization of the fork.**
+
+The synchronization of the fork will be done by the golangci-lint maintainers only.
