default.vcl insufficient

[Tim Kientzle]

According to the "Getting Started" guide on the website, I should be  
able to just run varnish with the default VCL, but that doesn't  
actually work.  I get this error:

  "No backends or directors found in VCL program, at least one is  
necessary.
   VCL compilation failed"

I recommend that the "backend default" definition in default.vcl be  
uncommented in order to make it easier for people to get started.
