[aur-general] Is it OK to provide the binary inside the PKGBUILD?

[Karol Blazewicz]

I noticed mp4join doesn't provde an upstream url and the PKGBUILD
looks ... interesting:
https://aur.archlinux.org/packages/mp/mp4join/PKGBUILD

package() {

cat << 'ENDEVOMGELAENDE' | openssl base64 -d > mp4join

<code goes here>

ENDEVOMGELAENDE
  chmod 755 mp4join
  install -D -m755 ./mp4join "${pkgdir}/usr/bin/mp4join"
}


Is it kosher?
