Wasn't sure which category to add this, if this belongs elsewhere please move.

I am wondering if the following function could become part of PKGBUILD/makepkg natively. I found it in another PKGBUILD and it is nice to use to allow split pkgs to move dirs/files easily into other package-*(){}
example say we want to move usr/share/docs into package_pkg-doc()
package() {
....
cd "$pkgdir"
pick docs usr/share/docs
}

package_pkg-doc() {
...
mv docs/* "$pkgdir"
}
pick() {
local p="$1" f d; shift
for f; do
d="$srcdir/$p/${f#$pkgdir/}"
mkdir -p "$(dirname "$d")"
mv "$f" "$d"
rmdir -p --ignore-fail-on-non-empty "$(dirname "$f")"
done
}
