# Generic version-check override.
#
# The CI test framework (test_entrypoint.sh) runs this once per sub-package
# with PKG_NAME / PKG_VERSION exported. Returning 0 means "version OK / not
# applicable"; a non-zero exit fails the package.
#
# Most lxc-* tool binaries print only the bare version number (e.g. "7.0.0")
# on --version via the shared tools/arguments.c parser, which we match below.
# The exceptions, which expose no usable version string, are skipped:
#   lxc-config       - custom arg parser, no --version (prints config items)
#   lxc-usernsexec   - plain getopt ("m:hsu:g:"), no --version flag
#   lxc-checkconfig  - shell script, prints no machine-readable version
#   lxc-monitord     - libexec helper, no --version flag
#   lxc-user-nic     - libexec helper, no --version flag
#
# Meta/library/script packages that ship no versioned executable are also
# skipped; their functionality is covered by the build itself.
