# vpdmn: Podman-like interface for cross-architecture container operations
#
# This provides a familiar podman-like CLI that executes commands inside
# a QEMU-emulated environment with the target architecture's Podman.
#
# Command naming convention:
# - Commands matching Podman's syntax/semantics use Podman's name (import, load, save, etc.)
# - Extended commands with non-Podman behavior use 'v' prefix (vimport)
# Set runtime-specific parameters before sourcing common code
