+A simple mechanism should be developed which "watches" a garage directory or
+file for changes. This mechanism has too sides.
+
+## Producer
+
+When making a change to a file in garage (putting or deleting) the producer
+should publish the path to that file to a bucket-specific pubsub channel on
+NATS.
+
+This only applies for file changes which are expected to have a watcher.
+
+## Watcher
+
+The watcher is a simple mechanism which looks like this:
+
+```go
+type Watcher interface {
+    Wait(context.Context) (string, error) // returns the path to the changed file
+}
+```
+
+It can be initialized with either a specific file path or a doublestar matcher.
