.order
The order file specifies the order that selected topics are displayed in the output EPOC help database. Other topics are displayed alphabetically by topic title, and are displayed after the ordered topics.
The order file is a plain text file consisting of a list of order names.
Each topic may, or may not, have an order name defined in the source .rtf
see Hypertext anchor. When the help file is generated, topics are re-ordered according to the position of their order name in the order file.
