CocoaWget is a front-end application for GNU wget. You can use it to download entire websites or parts of websites for offline viewing. wget is included in CocoaWget, so you do not need to prepare wget.
CBX322 This app comes with newest wget 1.10.2 works fine except one thing:
Preferences -> Options -> only a single option is recognized, i.e. if you add:
--no-check-certificate --no-dns-cache
in that field, the app gives an error: '--no-check-certificate --no-dns-cache' option unrecognized. This might be a problem with a variable, interpreting the string only as one option.
