Here is a beta version of what is to be 1.8. In this case, "beta" does not mean instability, just that I'd like a wider audience to take a look at the thing before we can call it a "prerelease". In either case, I'm aiming for a release soon, possibly within the week.
Get it from: ftp://gnjilux.srk.fer.hr/pub/unix/util/wget/.betas/wget-1.8-beta1.tar.gz (The `.betas' directory is intentionally unreadable, but the file is there.)
