Makefile for AUR maintainers: check upstream versions, bump pkgver, regenerate checksums and build in clean chroot across multiple packages.

Makefile

# AUR package maintenance Makefile
# Place this in the parent directory containing one subdir per package.
#
# Usage:
#   make check            — check all upstream versions
#   make bump             — update pkgver/pkgrel in PKGBUILDs
#   make checksums        — regenerate checksums
#   make build            — build all packages in clean chroot
#   make update           — full pipeline: bump + checksums + build
#   make <target> PKG=x   — restrict any target to a single package
