+      Daemon turns other process into daemons. There are many tasks that need
+      to be performed to correctly set up a daemon process. This can be tedious.
+      Daemon performs these tasks for other processes. This is useful for
+      writing daemons in languages other than C, C++ or Perl (e.g. /bin/sh,
+      Java).
