+A window has an appearance. This appearance can be specified when a window is being created. 
+To determine the appearance of a window there is a structure named nana::appearance with 
+a bool member for each feature with can be included or excluded in the "apereance" of the windows form.

+\code{.CPP}
+    nana::form form(x, y, width, height, nana::appearance(false, false, false, true, false));
+\endcode
+
+This piece of code may be confusing because of the 5 parameters of the constructor of `nana::form`. So the library provides a helper class for making it easy.  
+For better readability and understandability Nana provides three templates classes to generate an appearance object: 
+nana::appear::decorate, nana::appear::bald and nana::appear::optional. Each provide an operator 
+that return a corresponding nana::appearance with predefined values.
