+# This file determins which Lua version is used as a dependency for
+# a package.
+#
+# === User-settable variables ===
+#
+# LUA_VERSION_DEFAULT
+#	The preferred lua version to use.
+#
+#	Possible values: 51 52
+#	Default: 52
+#
+# === Infrastructure variables ===
+#
+# LUA_VERSION_REQD
+#	Lua version to use. This variable should not be set by
+#	packages; it is ordinarily set by multiversion builds.
+#
+#	Possible values: ${LUA_VERSIONS_ACCEPTED}
+#	Default: ${LUA_VERSION_DEFAULT}
+#
+# === Package-settable variables ===
+#
+# LUA_VERSIONS_ACCEPTED
+#	The Lua versions that the package can build against. Order
+#	is significant; those listed earlier are preferred over those
+#	listed later.
+#
+#	Possible values: 51 52
+#	Default: 52 51
+#
+# LUA_VERSIONS_INCOMPATIBLE
+#	The Lua versions that the package *cannot* build against.
+#
+#	Possible values: 51 52
+#	Default: <empty>
+#
+# LUA_SELF_CONFLICT
+#	If set to "yes", CONFLICTS entries are added among the various
+#	per-Lua-version variants of a multiversion package.
+#
+# === Defined variables ===
+#
+# LUA_PKGPREFIX
+#	The prefix to use in PKGNAME for multiversion packages.
+#
+#	Example: lua51
+#
+# Keywords: Lua
