I am trying in a wiki to "manually," i.e. not using the web interface, use the "page/index.html" type of page creation.
In my working clone src dir I can use, in succession, commands such as:
git add MyNewPage MyNewPage/index.mdwn
[here I edit the new index.mdwn]
git commit -a
These are, roughly, the steps I have taken, and they seem to work. But surely there is a more elegant, Ikiwiki-ish solution.
