OUTPUTFILE
FILE, SAVE_TO_VARIABLE
This function will read the contents of a file and output it to the screen. If the SAVE_TO_VARIABLE is set then the contents will be stored in that variable.
NOTE: you will need to set permissions so you can read the file from the local server.
Example
OUTPUTFILE "_ROOT/kytschi/omega_doom/gfx/intro/game-title1.gfx"
