This program is for editing the contents of EPUB files
right on PocketBook devices.  It is a shell script, so
it should run on any model.  It does require other
programs, which are model dependent:

Pi	  Yury Fedorchenko's text editor: <http://fedorchenko.net/pi.php>
zip   Infozip compression program: <http://www3.telus.net/rkomar/zip/>
unzip Infozip decompression program: <http://www3.telus.net/rkomar/pbimageviewer/unzip/>
sh_ivtool  Inkview UI elements for scripts: <http://www3.telus.net/rkomar/sh_ivtool/>

Install zip, unzip, sh_ivtool, and the edit-epub.app script into
/mnt/ext1/system/bin/, and Pi into /mnt/ext1/applications/.  Add
edit-epub.app to the list of applications for EPUB files in
/mnt/ext1/system/config/extensions.cfg, and then you can choose
it from the "Open" menu to edit EPUB files.

N.B.  Windows users: see <http://www3.telus.net/rkomar/edit-epub/crlf.html>
before downloading to ensure that the edit-epub.app script will work on
the PocketBook reader.
