 Hamlib (the ham radio control libraries)
 
-Hamlib is a development effort to provide a consistent C language
-interface for programmers wanting to incorporate radio controls
-in their programs.  Network daemons for radio and rotator control,
-along with language bindings for C++, Perl, Python, and TCL are
-included.
+Hamlib is a development effort to provide a consistent C language interface
+for programmers wanting to incorporate radio controls in their programs.
+Network daemons for radio and rotator control, along with language bindings
+for C++, Perl, Python, TCL, and Lua are included.
 
-Although this release of Hamlib includes an Lua language binding,
-the lua package from slackbuilds.org is 5.1.5 but 5.2 or newer
-is required.  Consequently, the Lua binding has not been included
-in this Slackbuild script.
+Optional language bindings
 
+To build either or all of the Perl, Python, or TCL bindings, pass one of or in
+combination:
+
+        PL_MOD=yes
+        PY_MOD=yes
+        TCL_MOD=yes
+
+to the build script.
+
+Optional Lua binding
+
+Also available are bindings for Lua 5.2 or later.  As Lua 5.2 and Lua 5.3 are
+now available from SlackBuilds.org, once the preferred version of Lua is
+installed, the Lua bindings may be built by passing:
+
+           LUA_VER=5.2
+           LUA_VER=5.3
+
+to the build script.
+
+Optional Python3 binding (experimental)
+
+For those wishing to experiment with Python3 and Hamlib, bindings may be built
+(exclusive of the normal Python2 bindings) after Python3 is installed
+(available from SlackBuilds.org) by passing:
+
+           PY3_MOD=yes
+
+to the build script.  This option overrides PY_MOD.
+
+While Python allows for version 2 and 3 modules to be installed concurrently,
+and while there does exist a method for doing so with Hamlib, that has not
+been included in this build script at this time.  If concurrent installation
+is needed, please contact the build script maintainer.
+
+All four bindings (either of the Python and either of the Lua versions) may be
+passed to the script to enable all bindings at build time.
