# Terminology:
# Crash privacy - Attempts to not send identifying information in the crash dump / to protect the obscurity of the program control flow
# MERP - The MS telemetry profile. Not for general use.
# Structured crashes - crashes at runtime that trigger a stack walk by mono that happens cooperatively
# Structured crashes are not merp crashes. Structured crashes are json dumps made by mono during crashes. Merp upload is going to use the dumping code is a very specific way, and is enabled at runtime with an icall.
#--with-crash_privacy=yes --with-structured_crashes=no means we don't wanna dump in non-merp-enabled builds, and we want to not send symbol strings. This is going to be the default pair of settings for VS4Mac.
#--with-crash_privacy=yes --with-structured_crashes=yes means you want to see crashes on your console, and you want to not see unmanaged symbol names. This is an option for proprietary apps that have manual bugs filed.
#--with-crash_privacy=no --with-structured_crashes=no means you want to see no crash dumps on failure and you don't care about privacy. This is how you'd set a "don't want it, don't care" configuration.
#--with-crash_privacy=no --with-structured_crashes=yes means you want full crashes and you want to see them in the terminal, not on telemetry. This is going to be how we build for CI.
