West: Explained in Simple Words
summary
West is a lightweight, Python-based meta-tool that manages Zephyr’s many git repos via a central manifest west.yaml and three workspace layouts (T1/T2/T3) so apps fetch only needed modules instead of downloading the whole multi‑GB tree. It standardizes build/flash/debug with commands like west build / west flash, produces RAM/ROM and static stack reports (Puncover), and lets projects add custom Python commands via west-commands.yaml so vendor tooling and bootloader+app builds run uniformly and reproducibly.
