+         This option causes busybox shells [currently only ash]
+         to not execute typical fork/exec/wait sequence, but call <applet>_main
+         directly, if possible. (Sometimes it is not possible: for example,
+         this is not possible in pipes).

+         This will be done only for some applets (those which are marked
