[Gretl-users] download a zip archive via script?

Hi, I'm wondering whether a hansl script can download a zip archive, and ideally also unzip the archive to save the various include files. I don't think it's possible, but then I don't understand the curl() function very well, and so I thought I might ask. I know that readfile() for example can handle zip compression, but I believe that only applies to a single file, not an archive. (It's clear that it's fairly simple by invoking external tools, e.g. through the 'foreign' interface. That's not my question.) thanks sven
