.get_rich_meta_info_from_script(dir, session = nil, options = {}) ⇒ Object

IMPORTANT#################################################### # get_rich_meta_info_from_script only works with zillabyte apps:push now! The pipe "info_to_ruby.in" is # hardcoded as the meta info passing pipe, so if 2 processes are trying to access it simultaneously there might # be problems since it gets created/destroyed within this script (attempting to create a fifo that already # exists or deleting a fifo that still has information in it may occur). # # IMPORTANT####################################################
