+
+#
+# Variables used
+#
+# LUA_VERSION currently installed version of Lua
+# LUA_LIBDIR ${LIBDIR}/lua/${LUA_VERSION}
+#
+# LUA_MODULES list of Lua modules to build/install
+# LUA_DPLIBS shared library dependencies as per LIBDPLIBS
+# (liblua is automatically included)
+#
+# LUA_SRCS.mod sources for each module (by default: "${mod:S/./_/g}.lua")
+#
+# DPADD additional dependencies for building modules
+# DPADD.mod additional dependencies for a specific module
+#
+#
+# HAVE_LUAC if defined, .lua source files will be compiled with ${LUAC}
+# and installed as precompiled chunks for faster loading. Note
+# that the luac file format is not yet standardised and may be
+# subject to change.
+#
+# LUAC the luac compiler (by default: /usr/bin/luac)
+#
+#
+# Notes:
+#
+# currently make(depend) and make(tags) do not support .lua sources; We
+# add Lua sources to DPSRCS when HAVE_LUAC is defined and other language
+# sources to SRCS for <bsd.dep.mk>.
+#
+# other language support for other than C is incomplete
+#
+# C language sources are passed though lint, when MKLINT != "no"
+#
+# The Lua binary searches /usr/share/lua/5.1/ at this time and we could
+# install .lua modules there which would mean slightly less duplication
+# in compat builds. However, MKSHARE=no would prevent such modules from
+# being installed so we just install everything under /usr/lib/lua/5.1/
