Re: Too few up-to-date CD image mirrors

I have one sorta kinda working. I'll pound on it a bit more before
releasing it. The overall inconsistency makes it hard, since right now
mirrors use a variety of directory structures and names of files (and
even do things like symlink the non-us cd image #1 to image #1). So my
script will not find every mirror that has isos, but only those that
have them in the semi-standard structure of:

3.0_r0/<arch>/debian-30r0-$arch-binary-<nnn>.iso

Just to give an idea (jigdo checking is probably still not working):

I've never seen a web browser that couldn't do an anonymous ftp login without
the user even noticing it went on. And not all of the http mirrors use standard
apache dir listing; some use crazy and broken dir listing that ends up looking
like this in a web browser:

   i386 -> jigdo

And that confused me, anyway, to no end (isos are actually hidden under 
the i386 link; jigdo is not a subdirectory of it).

Anyway, parsing http directory listings is too hard, so my script will 
only do ftp.

Yes, the current situation is crazy, and I just cannot understand why
cdimage.d.o has not been redirected to one of the mirrors that already has
everything, long since.
