How does SAOL work ?  like Csound ? i.e with an orc and sco ??

I dowloaded SAOL for Win95 but I couldn't compile with the -orc neither
-sco command....
instead it DID work with the -bitstream vowels.mp4 command....

Saol took the mp4 file and used to proper vowels.sao and vowels.sasl files
!

My question is :  if I need an mp4 file to compile saol orc and sco's, how
can I make them ???
