# lifinit --

#       -vnnn   Sets volume size to nnn bytes.

#               nnn must be a multiple of 256.

#       -d      Sets directory size to nnn file entries.

#               nnn must be a multiple of 8.

#       -nsss   Sets the volume name to be sss.

#       -Knnn   Forces the directory start location to be the

#               nearest multiple of nnn x 1024 bytes.

#       -snnn   set the initial system load (ISL) start address to

#               nnn in the volume label

#       -lnnn   Specifies the length in bytes of the ISL code.

#               beginning of the ISL

#

# lifcp --

#       -r      Forces RAW mode copying.

#       -T      Sets the file type of the directory entry.

#               ASCII is 1

#               BIN is -23951

#               BINARY is -2

#       -Knnn   forces each file copied in to begin on a nnn x

#       Note: the word echoed below MUST be 10 characters exactly.
