# How to Use The most basic invocation, e.g. `incremental_build.sh -- libc`, is logically equivalent to 1. running `m --skip-soong-tests libc` and then 2. parsing `$OUTDIR/soong_metrics` and `$OUTDIR/bp2build_metrics.pb` files 3. Adding timing-related metrics from those files into `out/timing_logs/metrics.csv` 4. repeat 1-3 for each CUJ CUJs are defined in `cuj_catalog.py` Each row in `metrics.csv` has the timings of various "phases" of a build. Try `incremental_build.sh --help` and `canoncial_perf.sh --help` for help on usage.
