#
# This script contains all steps necessary to:
#
#   * Build OBS with all required dependencies
#   * Create 64-bit and 32-bit variants
#
# Parameters:
#   -Help                   : Print usage help
#   -Quiet                  : Suppress most build process output

#   -BuildDirectory         : Directory to use for builds
#                             Default: build64 on 64-bit systems
#                                      build32 on 32-bit systems
#   -BuildArch              : Build architecture to use (x86 or x64)
#   -BuildConfiguration     : Build configuration to use
#                             Default: RelWithDebInfo
