Editorial note The chapter and some other chapters of this manual have been updated in August 2003, especially to take into account &opie; 1.0 release. But it is difficult for the &opie; team to keep up with &opie; and &opie; applications progress. Please indulge this manual occasional tardiness! Please note, also, that the end of this guide (from late Chapter 2 on) is incomplete, when it comes to documenting applications. In particular, the following applications still have an empty page: appearance2, appskey, calibrate, citytime, drawpad, handwriting, helpbrowser, kjumpx, language, lightpower, login, multikey, pickboard, player2, qpdf, reader, rotation, sheet, showimg, sshkeys, sysinfo, tableviewer, and write. Hopefully their interface is clear enough so you won't need documentation so much :-)
