In fact the history is stored in two separate files in Changi's working directory. One is named history.pag, a simple text file where each line corresponds to one article. The lines are kept in the order in which the articles have been received.
In addition to this text file, there is a database index named history.idx. This binary file contains the message id of each article together with an offset into history.pag.
Each line in history.pag consists of two or four fields separated by spaces.
