\section{\class{wxHtmlHelpController}}\label{wxhtmlhelpcontroller}
-{\bf WARNING! This help controller has an API incompatible with wxWindows
-wxHelpController!}
-
This help controller provides an easy way of displaying HTML help in your
-application (see {\it test} sample). The help system is based on {\bf books}
+application (see {\it test} sample). The help system is based on {\bf books}
(see \helpref{AddBook}{wxhtmlhelpcontrolleraddbook}). A book is a logical
section of documentation (for example "User's Guide" or "Programmer's Guide" or
-"C++ Reference" or "wxWindows Reference"). The help controller can handle as
+"C++ Reference" or "wxWidgets Reference"). The help controller can handle as
many books as you want.
+Although this class has an API compatible with other wxWidgets
+help controllers as documented by \helpref{wxHelpController}{wxhelpcontroller}, it
+is recommended that you use the enhanced capabilities of wxHtmlHelpController's API.
+
wxHTML uses Microsoft's HTML Help Workshop project files (.hhp, .hhk, .hhc) as its
native format. The file format is described \helpref{here}{helpformat}.
Have a look at docs/html/ directory where sample project files are stored.
You can use Tex2RTF to produce these files when generating HTML, if you set {\bf htmlWorkshopFiles} to {\bf true} in
-your tex2rtf.ini file.
+your tex2rtf.ini file. The commercial tool HelpBlocks (www.helpblocks.com) can also create these files.
+
+\wxheading{Note}
-In order to use the controller in your application under Windows you must
-have the following line in your .rc file:
+It is strongly recommended to use preprocessed {\bf .hhp.cached} version of
+projects. It can be either created on-the-fly (see
+\helpref{SetTempDir}{wxhtmlhelpcontrollersettempdir}) or you can use
+{\bf hhp2cached} utility from {\it utils/hhp2cached} to create it and
+distribute the cached version together with helpfiles. See {\it samples/html/help}
+sample for demonstration of its use.

Adds book (\helpref{.hhp file}{helpformat} - HTML Help Workshop project file) into the list of loaded books.
This must be called at least once before displaying any help.

You should list all pages in the contents file.
\membersection{wxHtmlHelpController::ReadCustomization}\label{wxhtmlhelpcontrollerreadcustomization}
Sets the path for storing temporary files - cached binary versions of index and contents files. These binary
forms are much faster to read. Default value is empty string (empty string means
-that no cached data are stored). Note that these files are {\it not}
+that no cached data are stored). Note that these files are {\it not}
deleted when program exits.
+Once created these cached files will be used in all subsequent executions
