# Host-side harness for packaging/void: runs the container flow (see
# container-main.sh and container-build.sh) in the pinned Void glibc
# container via podman, never Docker.
#
# Usage: packaging/void/build.sh <pkgname> [-- <xbps-src args...>]
#
#   packaging/void/build.sh python3-pywhispercpp
#   packaging/void/build.sh python3-pywhispercpp -- -o ~vulkan pkg
#
# Anything after -- is passed to `xbps-src` before the package name (use it
# for -o ~vulkan CPU-only rebuilds). The package build itself fetches
# nothing from the network beyond the template's declared distfiles:
# xbps-src verifies distfile checksums before unpacking.
