Bug#647403: please add a pointer to the installer source code to the docs

[Marc Haber <mh+debian-packages@zugschlus.de>]

Package: debian-installer
Severity: wishlist

Hi,

I recently found the installer docs (particularly the part about
preseeding) slightly terse and dared to ask two questions about
preseeding on IRC.

I was rather rudely pointed towards the web interface of the installer
git.

I would like to suggest a "read the source luke" paragraph to the
Installation Guide. This should obviously be a stable link to the
installer as it is used in stable to be valid reference.

Greetings
Marc
