+The configgen tool is used to:
+- generate the parser for the configuration file based on 
+  the templates config_templ.h and config_templ.l
+- generate the GUI frontend "doxywizard" for creating a configuration 
+  file based on the templates doxywizard_templ.h and doxywizard_templ.cpp
+
+If you want to add a new configuration option to doxygen,
+then you should add a new entry the init() function in configgen.cpp
+
+After that you can do a "make install" in this directory to update 
+the config.l and config.h in doxygen's source directory.
