# packages/passt/passt.SlackBuild
#
# Builds the passt/pasta .txz package from upstream source (C, plain
# Makefile — no autotools). passt is Podman's modern unprivileged
# user-mode network transport for rootless containers, superseding
# slirp4netns (see versions.env for why this project pins it via a git
# commit snapshot rather than a tagged release: upstream has no GitHub
# mirror and does not use semver tags).
#
# Requires (in the build environment): gcc, make. No external library
# dependencies beyond libc — passt deliberately avoids them.
