Sending output to world.log may be useful for debugging purposes. The output goes to the same place run-time proc errors are displayed.
if(1+1 != 2)
world.log << "Uh oh."You can assign world.log to a file name or file() object to redirect output to that file. (There is also a command-line option to Dream Daemon that does this.)
world.log = file("mylog.txt")
