+#
+# The following variables can be defined in a port that uses the Lua library,
+# tolua, Ruby bindings or related components like .lua modules (with run
+# and/or build dependencies). It can be used after and/or before
+# bsd.port.pre.mk, but Ruby components will only work if Ruby variables (e.g.
+# USE_RUBY) are defined before it (this is a bsd.ruby.mk limitation), at least
+# it is manually included.
+# USE_LUA		- Set to the list of Lua versions that can be used by the
+#				  port. The syntax allows the following elements:
+#				  - Single version (e.g. "4.0").
+#				  - Range of versions (e.g. "5.0-5.1"). Must be ascending.
+#				  - Partial range: single version and upper (e.g. "5.0+").
+#				  - Partial range: single version and lower (e.g. "5.1-").
+#				  Multiple elements can be specified separated by spaces.
+# USE_LUA_NOT	- Set to the list of Lua versions that can't be used by the
+#				  port. In other words, it removes some versions from USE_LUA.
+#				  If the latter is not defined, it will have the value of all
+#				  the possible versions. The syntax is like USE_LUA.
+# LUA_COMPS		- Set to the list of Lua components the port uses. Several
+#				  components can be specified separated by spaces. By default
+#				  it will have the value of "lua". Suffixes in the form ":xxx"
+#				  may be added to the components to determine the dependency
+#				  type.
+#				  The available components are:
+#				  lua			- The Lua library.
+#				  tolua			- The tolua library (vers 4.0-5.0).
+#				  ruby			- The Ruby bindings for Lua (vers 4.0-5.0).
+#				  app, compat51, dfui, filename, gettext, posix, pty and
+#				  socket		- Modules for Lua 5.0.
+#				  The available dependency types are:
+#				  build			- Requires component for building.
+#				  lib			- Requires component for building and running.
+#				  run			- Requires component for running.
+#				  If no suffix is present then "lib" will be used for "lua"
+#				  4.0-5.0 and "ruby", "build" for lua 5.1 and "tolua" (they
+#				  are static), all others default to "run".
+# LUA_PREMK		- Define to determine version and define variables after
+#				  <bsd.port.pre.mk> (in case the port needs to manually run
+#				  the Lua program or the like).
+# WANT_LUA		- Set to "yes" or a valid single version (no ranges, etc).
+#				  In both cases it will detect the installed Lua components
+#				  and add them to the variable HAVE_LUA. If a version is
+#				  selected, HAVE_LUA will contain a list of components in the
+#				  other case it will contain a list of "component-version"
+#				  pairs (e.g. lua-4.0, tolua-5.1, etc).
+#				  It has to be used before bsd.port.pre.mk.
+# WANT_LUA_VER	- Set to the prefered Lua version for the port. It must be
+#				  present in USE_LUA or missing in USE_LUA_NOT. This is
+#				  overriden by the user variable WITH_LUA_VER if set. It can
+#				  contain multiple versions in order of preference (last ones
+#				  are tried first).
+#
+# The following variables are intended for the user and can be defined in
+# make.conf.
+# WITH_LUA_VER	- Define to the list of prefered versions in reverse order.
+#
+# The following variables are defined by this file, to be read from the port.
+# HAVE_LUA		- The list of Lua components installed, if WANT_LUA was
+#				  defined. The components will have version suffix if it was
+#				  set to "yes".
+# LUA_VER		- The Lua version that is going to be used (e.g. "5.1").
+# LUA_VER_SH	- The Lua shared library major version (e.g. "1").
+# LUA_VER_STR	- The Lua version without the dots (e.g. "51").
+# LUA_PREFIX	- The prefix where Lua (and components) is installed.
+# LUA_SUBDIR	- The directory under bin/share/lib where Lua is installed.
+# LUA_INCDIR	- The directory where Lua and tolua header files are installed.
+# LUA_LIBDIR	- The directory where Lua and tolua libraries are installed.
+# LUA_MODLIBDIR	- The directory where Lua modules (.lua) are installed.
+# LUA_MODSHAREDIR	- The directory where Lua module libraries (.so) are
+#					  installed.
+# LUA_PKGNAMEPREFIX	- The package name prefix used by Lua modules.
+#
+# Examples:
+# - A port that needs Lua 4.0 and tolua (also 4.0) libraries (lua for building
+#   and running and tolua for building).
+#	USE_LUA=	4.0
+#	LUA_COMPS=	lua tolua
+# - A port that needs Ruby bindings for Lua 5.0 for building and running.
+#	USE_LUA=	5.0
+#	LUA_COMPS=	ruby
+# - A port that needs tolua 5.0 or 5.1 for building.
+#	USE_LUA=	5.0 5.1
+#	LUA_COMPS=	tolua
+# - A port that needs Lua version 5.0 or higher for building and running.
+#	USE_LUA=	5.0+
+# - A port that needs Lua of any version other than 5.1 for building and
+#   running.
+#	USE_LUA_NOT=5.1
