+% Define printobject and writeobject.
+% These are mostly implemented in PostScript, so that we don't have to
+% worry about interrupts or callbacks when writing to the output file.
+
+% Define procedures for accumulating the space required to represent
+% an object in binary form. The procedures for composite objects (arrays
+% and dictionaries) leave different results on the stack:
+% <#refs> <#chars> <simple_obj> -proc- <#refs> <#chars>
+% <#refs> <#chars> <array|dict> -proc- <array|dict> <#refs> <#chars>
+% This is required so that .writeobjects can also accumulate the actual
+% list of composite objects to write in the binary object sequence.
