and by friends I mean `mmp` and `btouch`
What does this do ?
1. Assume that output of `mtouch` (and other similar tools) is **always** of high importance. Why ?
- If not then it's not saved in the binary log (even if visible on the console/text logs).
- The logging of `mtouch` (and friends) is dynamic, based on a supplied verbosity level.
- If a verbosity level _anywhere_ then it's a clear sign that the developer wants that extra output (and that includes binary logs).
2. Assume the _global_ verbosity of `msbuild` from the console is just as valid/useful than the one from VSfM.
- CI/bots produce logs and they should be useful to diagnose build issues.
- Setting verbosity in several places is error-prone, which delay investigations and results.
- Running the same project, with the same `msbuild` verbosity, should be identical between IDE and console.
What does that mean ?
Using `msbuild /v:diag /bl:out.binlog` you get a small(er) binary log that has everything[1] you need to diagnose a Xamarin.iOS (or Mac) build. It's also identical to the output what VSfM produce (for the same `msbuild` verbosity level).
[1] we might need to review what we log if we're missing interesting stuff
