From the home page:
> Stop trusting blindly
> One-line installer scripts,
Here are the manual install instructions from the "Install / Build page:
> curl -L https://aur.archlinux.org/cgit/aur.git/snapshot/jai.tar.gz | tar xzf -
> cd jai
> makepkg -i
So, trust their jai tool, but not _other_ installer scripts?
