# macOS build script
##############################################################################
#
# This script contains all steps necessary to:
#
#   * Build OBS with all default plugins and dependencies
#   * Create a macOS application bundle
#   * Codesign the macOS application bundle
#   * Package a macOS installation image
#   * Notarize macOS application bundle and/or installation image
#
# Parameters:
#   -h, --help                     : Print usage help
#   -q, --quiet                    : Suppress most build process output
#   -v, --verbose                  : Enable more verbose build process output
#   -d, --skip-dependency-checks   : Skip dependency checks (default: off)
#   -b, --bundle                   : Create relocatable application bundle
#                                    (default: off)
#   -p, --package                  : Create distributable disk image
#                                    (default: off)
#   -c, --codesign                 : Codesign OBS and all libraries
#                                    (default: ad-hoc only)
#   -n, --notarize                 : Notarize OBS (default: off)
#   --xcode                        : Create Xcode build environment instead
#                                    of Ninja
