-# README:
-# This test validates two features of libs/daemon:
-# 1. The parent process does not wait for the child process to end.
-# 2. The child process correctly receives input from the parent process.
-#
-# Property (1) is validated because the child process waits for its parent process
-# to end before it writes to stdout.
-#
-# Property (2) is directly validated by the output of the child process.
-#
-# See the code for "selftest parent" and "selftest child" commands for more details.
