dofile – load and execute a Lua file
result = dofile(filename)
This looks for the given filename relative to the current directory (i.e. the directory containing the currently executing Lua script).
Assuming the file is found, it is then loaded and executed as a Lua chunk.
dofile returns any value(s) that are returned by the loaded chunk.
If the given file is not found, an error is raised.
If the loaded chunk raises any errors, then these errors are propagated by the dofile call.
