# - comment line
r <file> <file> - reads flist from file into buffer
i <number> - inserts flist from stdin into buffer (marker END)
d <flist> - displays flist
w <flist> <filename> - saves flist to file
l - lists bufs used

Any time an 'flist' is called for, the user can type a buffer number,
'incoming' (for the incoming output flist) or a file name to be read.
The opcode can be supplied numerically or symbolically (for example, '3' or
'PCM_OP_READ_OBJ' are equivalent).
