My suggestion of a single "tree" command was just that, where there would be a single "tree" command, and that command would require an option to make the differentiation between an red-black tree and a radix tree. I don't quite understand why you *only* have the "[-o] offset" advertised for the rbtree command? Virtually every instance of a radix_tree_root structure in the kernel is embedded in a data structure, similar to the typical usage of an rb_root. Why the difference? The "-H start" option should probably be something like "-R" for "root". When -H is used in the list command, it refers to list_[H]ead. The examples in the help pages are not particularly helpful. I don't know what "tts.rb" refers to? Can you find better examples that the user can relate to? Also, a clear explanation of what the "position information" actually means would be helpful.
