Discussed in https://chromium-review.googlesource.com/c/chromium/tools/depot_tools/+/6596109/comments/217e68b5_bcf66ede The warning message doesn't seem useful. This CL removes the warning message for caffeinate, but adds help message instead. This CL also refactors the help message for `autoninja --offline`. ``` > autoninja --help autoninja: -o/--offline temporary disable remote execution caffeinate: --no-caffeinate do not prepend `caffeinate` to ninja command usage: ninja [options] [targets...] ... ``` Change-Id: I152a144efbb6002e3bfb03b23d1e0eb2d3b2af1d Reviewed-on: https://chromium-review.googlesource.com/c/chromium/tools/depot_tools/+/6620110 Auto-Submit: Junji Watanabe <jwata@google.com> Reviewed-by: Nico Weber <thakis@google.com> Commit-Queue: Junji Watanabe <jwata@google.com> Reviewed-by: Adam Norberg <norberg@google.com>
