+ZEROMQ COMPATIBILITY
+--------------------
+The Crossroads library provides an optional drop-in 'libzmq' compatibility
+library for ZeroMQ applications. If your version of Crossroads was built with
+the `--enable-libzmq` option, you can find the compatibility library
+documentation in linkxs:zmq[7].

+NAME
+----
+zmq - Crossroads I/O ZeroMQ compatibility library
+
+
+SYNOPSIS
+--------
+*#include <zmq.h>*
+
+*cc* ['flags'] 'files' *-lzmq* ['libraries']
+
+
+DESCRIPTION
+-----------
+This 'libzmq' compatibility library is provided by the Crossroads I/O project
+as a transitional drop-in replacement for existing applications and language
+bindings written for the ZeroMQ library.
+
+The interfaces provided emulate those provided by ZeroMQ release 2.1.11, and
+binary compatibility is provided for ABI version 1.0.0.
+
+Existing applications can use these interfaces as a drop-in replacement for the
+ZeroMQ-provided 'libzmq' by installing the Crossroads version of this library
+in its place.
+
+Applications can also be recompiled against this library with no code or build
+system changes.
+
+IMPORTANT: The 'libzmq' compatibility library is an optional component of
+the Crossroads project, intended as a way to ease transition of existing
+applications and language bindings to the native 'libxs' interfaces, this
+feature will not be maintained indefinitely, hence developers are strongly
+encouraged to migrate their applications to 'libxs'.
+
+CONSTANTS
