+      ${FileAssociationFunction} "Param1" "Param2" "..." $var
+    [SectionEnd|FunctionEnd]

+_____________________________________________________________________________
+ 
+ ${RegisterExtension} "[executable]" "[extension]" "[description]"
+ 
+"[executable]"     ; executable which opens the file format
+                   ;
+"[extension]"      ; extension, which represents the file format to open
+                   ;
+"[description]"    ; description for the extension. This will be display in Windows Explorer.
+                   ;
+ 
+
