I would be better to quote it in mailing list mesasages for lazy users :-)

I see. Thanks.

What messages/menus are converted to use lua in your current patch?
(english.lua has only "hello" messages in current msg.mi.en file?)
It would be grate if we have more examples that have menu items.
(customize.lua and pkg.lua do that?)

181KB is large enough some poor RAMDISK based ports which have
kernel size restriction. If we can't remove old manuc/msgc right now
(or lua is larger than past), it would still cause less trouble
to keep USE_LUA option for such tier-II ports.

Probably you also have to add -llua in src/distrib/miniroot/list?
(and more MD list files, unless it's optional)

Thanks. I also hope people will see how lua can be used...
