The following aside in a post of KHMan quoted by Lorenzo Donati exposes
a gap in my knowledge.

I presume the remark means that the compile-to-bytecode part of LuaJIT
is faster than the corresponding part of Lua 5.1.
Now LuaJIT supplies a "luajit -jbc" control command, which lists the
bytecode but does not AFAICT offer an option to store it for later use.
I.e. there seems to be no LuaJIT equivalent of
luac -o foo.lbc foo.lua
True? And if so, surely debated on this list before my time?
