1# How to Use 2 3The most basic invocation, e.g. `incremental_build.sh --cujs "modify Android.bp$" -- libc`, is logically 4equivalent to 5 61. running `m --skip-soong-tests libc` and then 72. parsing `$OUTDIR/soong_metrics`, `$OUTDIR/bp2build_metrics.pb` etc 83. Adding timing-related metrics from step 2 into `out/timing_logs/metrics.csv` 94. Now it's "warmed-up", for each cuj: 10 1. apply changes associate with the cuj 11 1. repeat steps 1 through 3 12 13CUJs are defined in `cuj_catalog.py` 14Each row in `metrics.csv` has the timings of various "phases" of a build. 15 16Try `incremental_build.sh --help` and `canoncial_perf.sh --help` for help on 17usage. 18 19## CUJ groups 20 21Since most CUJs involve making changes to the source code, we group a number of cujs together such that when any of them is specified, all CUJs
