Usage:

${PROGNAME} [-h|--help] <baseline-build> <candidate-build> benchmarks... [-- gbench-args...]
Compare the given benchmarks between the baseline and the candidate build directories.
This requires those benchmarks to have already been generated in both build directories.
<baseline-build> The path to the build directory considered the baseline.
<candidate-build> The path to the build directory considered the candidate.
benchmarks... Paths of the benchmarks to compare. Those paths are relative to '<monorepo-root>'.
<baseline-build> The path to the build directory considered the baseline.
<candidate-build> The path to the build directory considered the candidate.
benchmarks... Paths of the benchmarks to compare. Those paths are relative to '<monorepo-root>'.
[-- gbench-args...] Any arguments provided after '--' will be passed as-is to GoogleBenchmark's compare.py tool.
