 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 generate MHHW projects (see wxHTML homepage for details).
+You can use Tex2RTF to produce these files when generating HTML, if you set {\bf htmlWorkshopFiles} to {\bf true} in
+your tex2rtf.ini file. The commercial tool HelpBlocks (www.helpblocks.com) can also create these files.
+
+\wxheading{Note}
+
+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.

 
 

-In order to use the controller in your application under Windows you must
