+A synchronization primitive, which allows fibers to wait until a particular condition is (edge) triggered. Zero or more fibers can wait on a condition. When the condition is signalled, the fibers will be resumed in order.
+
+## Example
+
+~~~ ruby
+require 'async'
+
+Sync do
+	condition = Async::Condition.new
+	
+	Async do
+		Console.info "Waiting for condition..."
+		value = condition.wait
+		Console.info "Condition was signalled: #{value}"
+	end
+	
+	Async do |task|
+		sleep(1)
+		Console.info "Signalling condition..."
+		condition.signal("Hello World")
+	end
+end
+~~~
+
+### Output
+
+~~~
+0.0s     info: Waiting for condition...
+1.0s     info: Signalling condition...
+1.0s     info: Condition was signalled: Hello World
