+ 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
+ NOFORK in include/applets.h).
+
+ This may significantly speed up some shell scripts.
+
+ This feature is relatively new. Use with care.
