What are the valid DNX --watch flag values?

I'm working on my first ASP.NET 5 application. When trying to start the application from the command line by running:

dnx web --watch

I get the following output:

System.FormatException: Value for switch '--watch' is missing.
   at Microsoft.Extensions.Configuration.CommandLine.CommandLineConfigurationProvider.Load()
   at Microsoft.Extensions.Configuration.ConfigurationBuilder.Add(IConfigurationProvider provider)
   at Microsoft.AspNet.Hosting.WebApplication.Run(Type startupType, String[] args)
   at Microsoft.AspNet.Server.Kestrel.Program.Main(String[] args)
--- End of stack trace from previous location where exception was thrown ---
   at System.Runtime.ExceptionServices.ExceptionDispatchInfo.Throw()
   at Microsoft.Dnx.Runtime.Common.EntryPointExecutor.Execute(Assembly assembly, String[] args, IServiceProvider serviceProvider)
   at Microsoft.Dnx.ApplicationHost.Program.<>c__DisplayClass3_0.<ExecuteMain>b__0()
   at System.Threading.Tasks.Task`1.InnerInvoke()
   at System.Threading.Tasks.Task.Execute()

What are the valid values for the --watch flag? I tried giving it a dummy value of 0 then changed some of my controller code, but the change was not reflected.

Update

To install dnx-watch run the following:

dnu commands install Microsoft.Dnx.Watcher

Then run your application by doing something like:

dnx-watch web

Arguments passed after the command name ("web" in your case) are arguments passed to that command. If you want arguments passed to DNX, pass them before: dnx --watch web

But, --watch will go away. Use dnx-watch instead: https://github.com/aspnet/Announcements/issues/74
