+  Summary: 'sbomnix is an open-source command-line tool for generating Software Bills
+    of Materials (SBOMs) for Nix-based software. It accepts Nix derivations, store
+    paths, result symlinks, and flake references as targets, and emits both SPDX
+    and CycloneDX JSON output.
+
+
+    By default, sbomnix generates SBOMs for runtime dependencies discovered from
+    realized build outputs. With `--buildtime`, it can instead generate SBOMs for
+    the buildtime dependency closure without requiring the target to be built.'
