I am trying to follow the guide for automating creation of a DMG for distribution of a macOS application but can't figure out how to get the ExportOptions.plist from a manual export. I am trying to follow this guide: https://developer.apple.com/documentation/security/customizing-the-xcode-archive-process What is a 'manual export' and what are the steps for creating a manual export. `# Ask xcodebuild(1) to export the app. Use the export options # from a previous manual export that used a Developer ID. /usr/bin/xcodebuild -exportArchive -archivePath "$ARCHIVE_PATH" -exportOptionsPlist "$SRCROOT/ExportOptions.plist" -exportPath "$EXPORT_PATH"` Where is "$SRCROOT" ? presumably I have to copy this ExportOptions.plist to this location. Thanks - I am sure this must be blindingly obvious because there seems to be no reference as to how you do this 'manual export' or where one finds the resulting options file.
