+Description.
+
+The StarOffice ActiveX control shows an example of access to UNO through COM technology.
+It requires a properly installed StarOffice version 6.0/6.1 or OpenOffice 1.0.
+This is a Lite ActiveX control so it can be used only in containers that
+allows to use such controls.
+
+Pressing to any link to staroffice document should activate the control.
+So the document will be opened in ReadOnly mode.
+
+Also it can be activated with an <OBJECT> tag from a html-page.
+Without any parameters for an object tag a new writer document will be
+opened for editing. Possible parameters are
+    src      - full URL to the file that should be edited/viewed;
+               it can contain "private:factory/..." URLs to open new documents
+			   for edit, for example "private:factory/swriter"
+    readonly - the default value is "true", in case it is set to any other
+               value the document is opened for editing
+
+As any ActiveX control this one should be registered.
+To let MSIE register it itself the "CODEBASE" parameter
+for the "OBJECT" tag should be specified
+with a URL to the library "so_activex.dll".
+The example of registration with "OBJECT" tag is in example.html.
+
+Also it can be done using regsvr32 application.
+To do it please write
+<Path to Windows installation>\System32\regsvr32 so_activex.dll
+
+To unregister the control please use /u option:
+<Path to Windows installation>\system32\regsvr32 so_activex.dll /u
