DESCRIPTION
          bpftool allows for inspection and simple modification of BPF objects
          on the system.

          Note that format of the output of all tools is not guaranteed to be
          stable and should not be depended upon.

OPTIONS
          -h, --help
                 Print short help message (similar to bpftool help).

          -V, --version
                 Print version number (similar to bpftool version).

          -j, --json
                 Generate JSON output. For commands that cannot produce JSON,
                 this option has no effect.

          -p, --pretty
                 Generate human-readable JSON output. Implies -j.

          -m, --mapcompat
                 Allow loading maps with unknown map definitions.

          -n, --nomount
                 Do not automatically attempt to mount any virtual file system
                 (such as tracefs or BPF virtual file system) when necessary.
