+   adapted; this is similar for new address types.
+
+   in the future i would like to have a more automatic assembling of socat from
+   topic oriented source files. this should make integration and control of
+   contributions more easy.
+
+   all code of a new topic - address and option definitions, open code, option
+   handing code, ev.parser code, etc. should go into one source file. the
+   selection of the desired code parts during the compilation is done by
+   setting cpp defines.
+
+   in the same was all public declarations should go in one header (.h) file.
