FYI,
I just realized that the foo.md files are entirely reasonable to edit for people who do not use Emacs or Org.
I learned of a tool , Pandoc, that can covert that .md to .org for me.
So....md may be the choice for sharing/editing documentation
But, I will need to write a PEG and actors to convert from markdown to CustomHelp.
I am going to finish the XPath work and start the SAX work before I tackle that.
I may also have to add a .gitignore on the .org files too to keep things easily in sync for the public.
cheers,
