+.SH MANIFEST and DATA-DIR
+When split-pages is 0, the manifest file describes how the final html page should be generated.
+
+By default, pdf2htmlEX will use the manifest in the default data-dir (run `pdf2htmlEX -v` to check), which gives a simple demo of its syntax.
+
+You can modify the default one, or you can create a new one and specify the correct data-dir in the command line. 
+
+When single-html is 1, all files referred by the manifest must be located in the data-dir.
