The title pretty much says it all: I'm looking for the "org source"1 for the page http://orgmode.org/manual/Installation.html. (I want to replicate several aspects of that page's formatting.)
Many org-mode documentation pages (e.g. here) have a Show Org Source button, but the page I'm interested in is not one of them.
What I'm not after is the HTML source that one can view by, for example, pointing one's browser to view-source:http://orgmode.org/manual/Installation.html.
1 Assuming, of course, that the web page in question was generated from an org document. This assumption could be incorrect; if so, please let me know.
