No binaries, no, no.  It would be a basic hand-patch type of deal, with
detailed instructions of how to alter the database functions in db.c and
OLC so they use MySQL instead of textfiles.  It would also give dumps of
MySQL tables so that people can just run them as queries to get up and
running quicker.

For instance, would this code be considered written by me, and without any
trace of GPL code?  All it has is the API function calls.

void init_mysql(void)
   log("Boot db -- Initiating MySQL connection.");
   if (!mysql_connect(&mysql,MYSQL_HOST,MYSQL_USERID,MYSQL_PASSWD))
     log(buf, "SYSERR: Failed to connect to MySQL: %s", mysql_error(&mysql));
   } else {
     log("Boot db -- MySQL connection established.");

That's a function I wrote so I could call it from comm.c's init_game().

Hooo-ha! I'd clicked accept just for the hell of it.
