+\section{\class{wxCountingOutputStream}}\label{wxcountingoutputstream}
+
+wxCountingOutputStream is specialized output stream which does not write any data anyway,
+instead it counts how many bytes would get written if this were a normal stream. This
+can sometimes be useful or required if some data gets serialized to a stream or compressed
+by using stream compression and thus the final size of the stream cannot be known other
+than pretending to write the stream. One case where the resulting size would have to be
+known is if the data has to be written to a piece of memory and the memory has to be
+allocated before writing to it (which is probably always the case when writing to a 
+memory stream).
