Please don't use longjmp.

You'll have to change the code to not die() upon connection failure,
but instead return an error code to the higher level which can
locate another mirror and retry.

With great pain.  :-)

To do a user menu you can do a simple interface like `git add -i`
does, which just dumps the choices to stdout and a prompt for the
user to enter their selection.  If you want something more complex
you need to link to curses or ncurses, which IIRC opens some issues
with portablity, but lets you do a bit nicer interface on the tty.
