+SUMMARY = "Userspace utilities for fs-verity"
+DESCRIPTION = "fs-verity is a Linux kernel feature that does transparent \
+on-demand integrity/authenticity verification of the contents of read-only \
+files, using a hidden Merkle tree (hash tree) associated with the file. The \
+mechanism is similar to dm-verity, but implemented at the file level rather \
+than at the block device level."
