- section of documentation (for example "User's Guide" or "Programmer's Guide" or
- "C++ Reference" or "wxWidgets Reference"). The help controller can handle as
- many books as you want.

+ - wxHF_FLAT_TOOLBAR: The help window has a toolbar with flat buttons (aka coolbar).
+ - wxHF_CONTENTS: The help window has a contents panel.
+ - wxHF_INDEX: The help window has an index panel.

+ - wxHF_OPEN_FILES: Allows user to open arbitrary HTML document.
+ - wxHF_PRINT: The toolbar contains "print" button.
+ - wxHF_MERGE_BOOKS: The contents pane does not show book nodes.
+ All books are merged together and appear as single book to the user.
+ - wxHF_ICONS_BOOK: All nodes in contents pane have a book icon.
+ This is how Microsoft's HTML help viewer behaves.
+ - wxHF_ICONS_FOLDER: Book nodes in contents pane have a book icon, book's
+ sections have a folder icon. This is the default.
+ - wxHF_ICONS_BOOK_CHAPTER: Both book nodes and nodes of top-level
+ sections of a book (i.e. chapters) have a book icon, all other sections
+ (sections, subsections, ...) have a folder icon.
+ - wxHF_EMBEDDED: Specifies that the help controller controls an embedded
+ window of class wxHtmlHelpWindow that should not be destroyed when
