# name is flua.
|

|

|
# LUA_CMD can be overwritten to point to a Lua that isn't flua. This is fine,
|
||
|
|
# but parts of the src build that use it may have certain expectations that
|
||
|
|
# may only be fulfilled by the in-tree Lua. The user overwriting it is expected
|

|
# to understand these and provide the expectations.

|
#
|

|
|
# The LUA variable should point to LUA_CMD on the system, if it exists.
