+define Package/obfs4proxy/Default/description
+obfs4proxy is a tool that attempts to circumvent censorship by
+transforming the Tor traffic between the client and the bridge. This way
+censors, who usually monitor traffic between the client and the bridge,
+will see innocent-looking transformed traffic instead of the actual Tor
+traffic.
+
+obfs4proxy implements the obfsucation protocols obfs2, obfs3, and obfs4.
+
+It is written in Go and is compliant with the Tor pluggable transports
+specification, and its modular architecture allows it to support
+multiple pluggable transports.
+endef
+
+define Package/obfs4proxy/description
+$(call Package/obfs4proxy/Default/description)
+
+This package contains both the client and the bridge in a single
+program.
