 Posted: Sat Jun 30, 2012 12:52 pm Post subject: Generating an Epub from the Gentoo Handbook |
 |
|
Hi,
I thought it would be nice to have an Epub ebook of the Gentoo Handbook. Since it could not be easily downloaded, I made a bash script, which depends on sed, imagemagick, zip and wget. It is by far not perfect, as no links in the book can be clicked. But it works for me... Changes/Improvements are welcome!
Note: Some lines were broken apart when I copied this script here. You can't just copy-paste this!

#!/bin/bash
# This script generates an epub file from the online Gentoo Handbook
# Dependencies: wget, ImageMagick,
# Usage: ./handbook2epub
# 1) Create directory structure
echo -n "1) Create directory structure "
