# Calls emul/zasm/zasm in a convenient manner by wrapping specified

|
# paths to include in a single CFS file and then pass that file to zasm.

# Additionally, it takes a "-o" argument to set the initial ".org" of the
|
|
# binary. For example, "zasm.sh -o 4f < foo.asm" assembles foo.asm as if it
|

# started with the line ".org 0x4f00".
