+<!-- 
+ ~ if comment should be started and closed by special symbols, then place them in
+ ~ a separate lines without any text
+ ~ And any symbols can be used as a prefix, it will be excluded from the text
+ ~
+ ~ @todo #34 Description can not be created in one line with comment
+ ~ symbols. Just use at least the same amount of the spaces, as on the first line.

+/**
+ * @todo #36 Multiline text can use the same prefix in all lines or the same 
+ *  amount of spaces.
+    So this will be added to the puzzle description. If you want to divide the 
+ *  puzzle by empty line, just add a space to that line  
+ *   
+ *  and continue the text after.
+ *
+ *  This line is not part of the puzzle, because the line before contains less
