Github supports org-mode files, and has a renderer that parses .org files
and converts them to HTML form. Headings appear in larger font, org tables
are converted to graphical HTML tables, etc.

Is there a way to control the way .org files appear on Github?

I tried adding some export options in the usual manner

#+OPTIONS:   H:2 toc:t

but the options are not reflected.

Is this possible?

If not, what's the best way to automatically push to the web the most
version of a locally stored org-mode file without having to Export to HTML
every time I make a change?
