How to read files "DAF" (double-precision file) "transfer"?

Question

I downloaded some data in the DAF “transfer” format, which NASA does not fully explain here:

http://naif.jpl.nasa.gov/pub/naif/toolkit_docs/C/req/daf.html#Conversion%20and%20Transfer%20of%20DAF%27s

How to read this file. Here are the first few lines I'm trying to understand:

According to NASA, this / was a popular format for Fortran programs, but google didn't help at all (wikipedia has no entry or).
