13# LUA_INSTALL_PATH and LUA_CMD describe where the internal lua has been
14# installed to, along with the name of the internal command.  The default
15# name is flua.
16#
17# LUA_CMD can be overwritten to point to a Lua that isn't flua.  This is fine,
18# but parts of the src build that use it may have certain expectations that
19# may only be fulfilled by the in-tree Lua.  The user overwriting it is expected
20# to understand these and provide the expectations.
21#
22# flua is currently equivalent to Lua 5.3, with the following modules:
23# - luafilesystem
24# - lua-posix

27LUA_CMD?=		flua

29#
30# Some standalone usage may want a variable that tries to find the lua command,
31# and cannot necessarily embed the logic for trying to find it amongst bootstrap
32# tools.  For these, we provide the LUA variable.
33#
34# The LUA variable should point to LUA_CMD on the system, if it exists.
35# Otherwise, consumers will have to settle for a PATH search and PATH being
36# appropriately set.
