Add devel/cligen:

cligen builds and interprets datastructures (a parse-tree) which a
library (libcligen) interprets in runtime. It is fast and efficient
and helps you develop CLIs easier. You enter a CLI syntax either in
a text file, you write callback functions where you call the right
library routines.
