This task does one thing, so I don't see how I could split it up. To 
write the necessary code it's essential to know what the reprepro 
commands do and what their syntax is. As a subtask you could write a 
patch with just comments for each of the Python statements in that code 
region to explain their purpose. Include examples of variable contents, 
shell commands and output where appropriate.

If you haven't yet played with reprepro, be sure to run some of the 
commands debderiver uses straigt from the shell. It's silly to work on 
an abstraction of a tool if you have no experience with the tool itself.
