This daemon is filled with ancient Cthuloid runes that convert helpful innocent admins into evil power-hungry admins. (You knew in your heart there was a reason, didn't you?) No, I lie. What this daemon actually does is help with converting user .o files to new formats when you change versions of user.c Usually you can handle changes by using consistency_check() in user.c but for major things connected with bodies and connection objects this is a cleaner way to go. You can invoke it by putting the line: CONVERTER_D->fix_user(str); in login.c 's get_name() before it checks for the user's existance.
