Very nice!
I like the way, you can see in github, what the result will look like. 

My take on the same subject can be found on gedasymbols.org :
http://www.gedasymbols.org/user/kai_martin_knaak/new_geda_project.sh

This is a script I actually use to start geda projects. So it provides a  
skeleton with a few more bones:
  * an empty schematic file with a project name, date and developer filled 
out in the title block.
  * an empty layout file with my preferred layer stack.
  * a doc directory with a lyx document that contains a number of standard 
sections for documentation
  * a print directory for rendered PDFs and print scripts. The print 
scripts may be modified to match the needs of the specific project.
  * a gerber directory for gerbers with a script that prepares the gerbers 
from the layout file.
  * a bom directory for the bill of materials and whatever additional 
information the assembler needs. 
  * a directory for files related to the enclosing. 3D CAD drawings, etc.
  * a directory for old versions of the project

In addition, my script optionally prepares a bare git repo to push to.
Looking at your skeleton-project I realize a major ommission in my 
approach: I don't arrange for symbols and footprints in local directories. 
This is in part, because I tend to embed symbols if a project is "ready" 
for the archive. That way, *.sch and *.pcb  are the only master files, 
from which everything else can be derived.

I found, Makefiles add to the barriers perceived by newbies. Even simple 
Makefiles like yours look like incomprehensible magic spells to the 
uninitiated. So I stick with the less elegant bash scripts.

Yes, documentation is a (very) weak spot in most of geda.

+1
Is there any high profile open hardware project that endorses geda?
