# using the chrome://tracing URL:
# - the '?' icon in the top-right is the help
# - 'gbuild' rows represent per-parallelism (per-CPU) usage in time
# - 'totals' rows represent sums for reach build type
# - note that 'EXTERNAL' targets do not detect whether the external package
# is built with parallelism or not, so the actual CPU time may be higher
# - vertical lines represent targets that themselves do not take any time
# to build
# - any target can be found using the search field in the top right corner
# (just type e.g. '[MOD]: sal' and hit the '->' button, if you cannot see
# it pressing 'm' or 'f' can help)
