It would be really Good to have "make scriptconfig SCRIPT=<path to script>" > and "make iscriptconfig" (similar to above, but shortened) in "make help" output. I have added short descriptions to "make help", mostly referring people to the script itself. Do you think I should explain it more fully? I felt bad about adding big blobs of text when the "make help" descriptions for all the other *config targets are short oneliners :) > > 2.
