We do not usually provide help for our internal scripts. Besides, such
help has a tendency to bitrot pretty quickly anyway.

-       Usage:
-           ${my_name} <-m|-k> -o FILE PATH
-
-       With -m, ${my_name} generates the makefile fragment that defines
-       variables related to the br2-external trees passed as positional
-       arguments.
-
-       With -k, ${my_name} generates the kconfig snippet to include the
-       configuration options specified in the br2-external trees passed
-       as positional arguments.
-
-       Using -k and -m together is not possible. The last one wins.
-
-       Options:
-           -m  Generate the makefile fragment.
-
-           -k  Generate the kconfig snippet.
-
-           -o FILE
-               FILE in which to generate the kconfig snippet or makefile
