how to get a sheet with chord names only?

[Peter]

I'm trying to produce a simple sheet with chord names in bars, without  
any notes or staff lines.

Something like this:

Then I found this snippet: http://lilypond.org/doc/v2.0/input/test/out-www/lily-1441517942.ly 
 and that was exactly what I needed! (the above image is from exactly  
that file)

Unfortunately, the snippet was for Lilypond 1.9.8 (although it was  
found under the 2.0 tree), and my installed version ( 2.11.45) did not  
like it... in particular, it didn't like \translator and  
\ChordNamesContext.

And convert-ly stated that the file was too old (oldest supported is  
2.7.38).

So now I'm a bit stuck...

Is there any kind soul that can point me in the right direction? I've  
been googling, searching the LSR, but I didn't find a clue.  Maybe I'm  
just looking in the wrong places or I'm simply glaring over the  
obvious, but I simply can't find it. Maybe I'm just plain stupid,  
that's another possibility, but I'm not willing to accept that yet :-)

Thanks,
Peter.
