   6 # Variables used
   7 #
   8 # LUA_VERSION   currently installed version of Lua
   9 # LUA_LIBDIR    ${LIBDIR}/lua/${LUA_VERSION}
  10 #
  11 # LUA_MODULES   list of Lua modules to build/installi
  12 # LUA_DPLIBS    shared library dependencies as per LIBDPLIBS
  13 #
  14 # LUA_SRCS.mod  sources for each module (by default: "${mod:S/./_/g}.lua")
  15 #
  16 # DPADD         additional dependencies for building modules
  17 # DPADD.mod     additional dependencies for a specific module
  18 #
  19 #
  20 # HAVE_LUAC     if defined, .lua source files will be compiled with ${LUAC}
  21 #               and installed as precompiled chunks for faster loading. Note
  22 #               that the luac file format is not yet standardised and may be
  23 #               subject to change.
  24 #
  25 # LUAC          the luac compiler (by default: /usr/bin/luac)
  26 #
  27 #
  28 # Notes:
  29 #
  30 # currently make(depend) and make(tags) do not support .lua sources; We
  31 # add Lua sources to DPSRCS when HAVE_LUAC is defined and other language
  32 # sources to SRCS for <bsd.dep.mk>.
  33 #
  34 # other language support for other than C is incomplete
  35 #
  36 # C language sources are passed though lint, when MKLINT != "no"
  37 #
  38 # The Lua binary searches /usr/share/lua/5.1/ at this time and we could
  39 # install .lua modules there which would mean slightly less duplication
  40 # in compat builds. However, MKSHARE=no would prevent such modules from
  41 # being installed so we just install everything under /usr/lib/lua/5.1/
