defmodule Appsignal.ErrorHandler do
@moduledoc """
Error handler which sends all crash reports to the AppSignal backend.
When you add `:appsignal` to your application's dependencies, this
error logger will automatically be installed. All processes that are
supervised, like GenServers, Tasks, Agents, Supervisored will be
monitored for crashes. In the case of a crash, the AppSignal error
handler collects error information and sends it to the backend.
