I have re-done the BB webABC site with a view to making it more "user-friendly", mainly by arranging the material in table format.
The "parent directory" is http://www.capeirish.com/webabc/. There’s a "quick read-me" file in there that will help you get started.
This whole endeavor is a (perpetual) "work in progress", so please let me have comments, suggestions, etc. that you think might be helpful.
