This is a hack, I fear. The good news is that Lua can call
external code in DLLs using loadlib(). The bad news is the
function returned by loadlib() doesn't accept any parameters.
So one has to copy the parameters to a temporary file,
call the function in the DLL, which writes to another temporary
file, which we then read. First thing to check is whether
the scite_other.dll has actually been loaded - it
should complain.

No problem. I'm still a very new Lua user. Would you mind expanding
on what exactly TEMP_FILE_IN and TEMP_FILE_OUT are used for in this
code? How do I use this with Scite?
Thanks a lot!
