+# FileSystemWatcher
+
+A bridge between Linux's C API [`inotify`](https://linux.die.net/man/7/inotify) and Swift.
+
+## Use cases
+
+For any async file system event monitoring, we gotcha.
+
+## Usage
+
+I made a [demonstration app](https://github.com/felix91gr/fswatcher-usage) of usage of this library.
+
+The most basic form of usage is as follows:
+
+```swift
+
+import FileSystemWatcher
+
+var eventCount : Int
+
+eventCount = 0
+
+func printEvent(event: FileSystemEvent) {
+	print("Hey! Something happened!!") 
+  // I'd love to use event.name, but I can't figure out yet how to read that from C's API
+	// That'd be useful for debugging purposes.
+  // But it's allright as long as you don't need to know the exact description of the ocurring events.
+  eventCount += 1
+}
+
+
+print("Starting!")
+
+let myWatcher = FileSystemWatcher()
+
+myWatcher.watch(
+	paths: ["/tmp"], 
+	for: [FileSystemEventType.inAllEvents],
+	thenInvoke: printEvent)
+
+
+myWatcher.start()
+
+readLine()
+
+myWatcher.stop()
+
+print("Total number of events: " + String(eventCount))
+
+print("Finished!")
+
+```
