# Note: o3de_pal_dir will take care of the details for us, as this may be a restricted platform
#       in which case it will see if that platform is present here or in the restricted folder.
#       i.e. It could here in our gem : Gems/MiniAudio/Code/Platform/<platorm_name>  or

# traits for this platform. Traits for a platform are defines for things like whether or not something in this gem
