eReader devices are becoming popular in the latest months. Some of them make use of the MobiPocket format (.prc, .mobi), similar to HTML but stored as a binary file and including pictures.

The advantage of such format is the reflow capability, that is, on the contrary to printed formats like PDF or PS, MobiPocket books (like HTML) are adapted to the width of the screen, allowing to resize the font to give the reader a more comfortable experience.

As of today, MobiPocket books are generated with the free but privative tool Mobipocket Reader or Mobipocket Creator, which is unfortunately only available for Windows.

The target of this project is to provide a command line tool to, given a OPML list of feeds, generate for each of them a MobiPocket book with their latest contents.

The implementation is done in Java, using the library Yarfraw and the Mobiperl tools.
