Have you any comments for the attached PKGBUILD?

[u26]

I wrote the following PKGBUILD by a trial and error process on another PKGBUILD.
It does seem to, well, do something. How far it is from a reasonable quality 
PKGBUILD?

_pkgname=northstar-web-browser
pkgname="${_pkgname}"
pkgver=1.0.16.r33.g19b27d5
pkgrel=1
pkgdesc="A minimalist web browser written from scratch in C"
arch=('x86_64')
url="https://nordstjernen.org/northstar-browser/";
license=('GPL-3.0-or-later')
depends=('gtk4' 'uchardet')
makedepends=('meson' 'cmake')
_srcdir="${_pkgname}"
options=('!debug' 'strip')
source=( 'git+https://github.com/nordstjernen-web/northstar-web-browser.git' )
sha256sums=('SKIP')

pkgver() {
  set -u
  cd "${_srcdir}"
  git describe --tag --long | sed -e 's:^v::g' -e 's/\([^-]*-g\)/r\1/' -e 
's/-/./g'
  set +u
}

prepare() {
  set -u
  cd "${_srcdir}"
  meson setup build
}

build() {
  cd "$pkgname"
  meson compile -C build
}

package() {
  cd "$pkgname"
  DESTDIR="$pkgdir" meson install -C build
}
