 # The GENERATE_TREEVIEW tag is used to specify whether a tree-like index 
 # structure should be generated to display hierarchical information. 
-# If the tag value is set to FRAME, a side panel will be generated 
-# containing a tree-like index structure (just like the one that 
-# is generated for HTML Help). For this to work a browser that supports 
-# JavaScript, DHTML, CSS and frames is required (for instance Mozilla 1.0+, 
-# Netscape 6.0+, Internet explorer 5.0+, or Konqueror). Windows users are 
-# probably better off using the HTML help feature. Other possible values 
-# for this tag are: HIERARCHIES, which will generate the Groups, Directories, 
-# and Class Hierarchy pages using a tree view instead of an ordered list; 
-# ALL, which combines the behavior of FRAME and HIERARCHIES; and NONE, which 
-# disables this behavior completely. For backwards compatibility with previous 
-# releases of Doxygen, the values YES and NO are equivalent to FRAME and NONE 
-# respectively.
