+# Support for tracing what gbuild does.
+# Run 'make GBUILD_TRACE=/somewhere/log.json', process the file
+# using solenv/bin/finish-gbuild-trace.py, and then view it in Chromium
+# 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)
