Note
If you are using Arch Linux and have a local copy of the Arch Build
System (ABS) tree on your computer, or are using another
distribution that provides a similar tree of build files, you can
copy the provided PKGBUILD.proto file to a new package build
directory and make customizations to suit your needs. An up to date
prototype file can also be found in the source distribution of this
package.

The protoype is provided by the pacman package and not ABS.
