+Another form of compression is offered using the LZ4 library.
+
+Tinc has support for the LZ4 compression algorithm as compression level 12.
+
+By default, tinc will try to link to an external LZ4 library. If it is not
+found on your system or its version is older than r129, then tinc falls back to
+the built-in copy of the library.
+
+You can force the use of the built-in copy by passing `--enable-lz4-builtin`,
+or disable it completely with `--disable-lz4-builtin`.
+
+LZ4 support can be completely disabled with `--disable-lz4`. Note that the
+resulting binary will not work correctly on VPNs where LZ4 compression is used
+by other peers.
