[arch-general] How to make aura more verbose?

Hello, trying to use aura instead of pacaur. Yesterday I started to install jitsi - it's still running (?). Well, it's also the first time I'm installing this package, so I don't know how much effort is needed for building. However, I'd like to see all the messages like with pacaur, but aura keeps to be silent, even with the -v option.  :-/ How can I switch the messages on? And are there any build logs I can watch? I'd prefer not to stop a build which is running several hours before making sure it really hangs. Kind regards Peter
