+    # Call the #open method on EM::DeferrableChildProcess, passing
+    # a command-string. #open immediately returns an EM::Deferrable
+    # object. It also schedules the forking of a child process, which
+    # will execute the command passed to #open.
+    # When the forked child terminates, the Deferrable will be signalled
+    # and execute its callbacks, passing the data that the child process
+    # wrote to stdout.
