Ah, ok, that helps tremendously.
I'm sure your NB would recognize that there's no "manufacturing processes" per se with software. I would probably still have this section, though, and note that it's a software-only product and reference the build documentation (which should provide sufficient information about the build environment controls and enable a re-build in the future!). Maybe even reference the Software Development Plan which outlines how releases are controlled. I would also describe how I ensure that the binaries from the build get to the right place and are confirmed correct. Should be pretty simple.
