Questions about Fennec (Firefox) for Harmattan
 

How can I build Fennec for Harmattan platform from sources on my own?
I (think I) found the most fresh sources here - https://github.com/tmeshkova - but I am not sure how to build it. In Scratchbox?
And also where can I find nightly versions of Fennec from romaxa's page? I encountered on links on few pages and forums. I was looking for it also in web.archive.org but nothing found.
Where to look for some useful informations or instructions? There was something on a Mozilla's wiki page but it have been removed some time ago.
