# Pros:
# - contains firing logic of any complexity
# Cons:
# - interface is different from Ports API

3_ClassicFBPPortBuffersProcess.coffee

## Define a process in Classic FBP style with direct input buffers
# Pros:
# - even more control over firing logic
# - closer to bare metal
# Cons:
# - verbose
# - may require proxying each port on each call
