I thought it was a good idea so I made this
It will download the last two days (can be changed, just change the 'DAYS' variable) worth of released cables, and it uses a hardcoded ip address instead of the DNS name.
EDIT: Now it uses one of a few mirrors... since apparently the IP is no longer working (DoSed?)

I tried now to make the linebreaks of the cables more readable (still sucks in some things, but it should be better now).
EDIT: Added karunaji's ideas (thanks!) to improve handling of linebreaks, as well as a couple other heuristics for the same thing.
