/*
 *  OPIE Notes
 *
 *  based on NoteZ 1.1.0 by Henning Holtschneider <hh@holtschneider.com>
 *
 *  moved to OPIE Pim framework by Marcin Juszkiewicz <openembedded@hrw.one.pl>
 *
 *  History:
 *  - 2005.10.12 - started work
 *  - 2005.10.19 - version 0.2:
 *                 - first working version
 *                 - info sent to NoteZ author and to OPIE devel
 *
 *  - 2005.10.20 - version 0.3:
 *                 - load/save in UTF-8
 *                 - load all files from Documents/text/plain
 *                 - create .txt files not .ntz - timestamp used as name
 *                 - one variable (documentsDirName) keep location of notes
 *                 - code (re)indented and converted to spaces
 *                 - variables translated to English (were in German)
 *                 - started work on beaming
 *
 *  - 2005.10.26 - version 0.4:
 *                 - added check does Documents/text/plain exist and create it if not
 *
 *  ToDo:
 *  - beaming
 *  - moving to SQLite database
 *  - category support
 *  - searching
 *
