  conversion/ConvertDirectory.java (bug-fix)
		It is checked whether file "index" is modified since the last
        conversion. This check was not performed before.  
  conversion/ConvertFile.java
		Some optimization there. Now we check if the file content is
        "empty" before we delve into conversion.        
  index/IndexCreator.java
		# "index" file is created in the directory, if it is not
		  created.
		# write() renamed to shouldConvert(). The method now returns
          true when a link is added to 'index' or when the index.html file
          does not exists.    
  io/ReadFile.java
		# Exception message for made verbose.
