Ah the macro expansion limit.
The limit is currently at 110K iirc. The buffer size is tunable in rpmio/macros.c,
the 110Kb is known to work for OpenPKG (which is using embedded lua extensively).
lua _IS_ a programming language, you should not be limited by whatever size
a macro expansion buffer is. If you do hit the limit, you should likely
change your approach to use, say, /tmp files! wotta concept!
