+    This cask will install only the ChmodBPF package from the current Wireshark
+    stable install package.
+    An access_bpf group will be created and its members allowed access to BPF
+    devices at boot to allow unpriviledged packet captures.
+    This cask is not required if installing the Wireshark cask. It is meant to
+    support Wireshark installed from homebrew or other cases where unpriviledged
+    access to OS X packet capture devices is desired without installing the binary
+    distribution of Wireshark.
+
+    The user account used to install this cask will be added to the access_bpf
+    group automatically.
