+Coding Style
+------------
+
+Before you submit your applet for inclusion in BusyBox, (or better yet, before
+you _write_ your applet) please read through the style guide in the docs
+directory and make your program compliant.

+Some Words on libbb

 As you are writing your applet, please be aware of the body of pre-existing
-useful functions in utility.c. Use these instead of reinventing the wheel.

+Placement / Directory

+Find the appropriate directory for your new applet.

+Add the applet to the applet directory Makefile:

-BB_FEATURE_TRIVIAL_HELP section, one flag per line. (Numerous examples of this
