I'd like to announce the availability of a script to download and package the latest version of Calibre. You can find it here:
https://gist.github.com/duganchen/a3bc1101e1a4a2bc8e47
Run it as root. It will download the latest version of Calibre (which, today, is 2.5.0), and package it. When it's finished, you'll have a correctly-named, installable package in $TMP (which is /tmp unless you've set it otherwise).
Don't worry about dependencies; they're all included.
When a new version of Calibre is available, just run the script again, and you'll have a package in $TMP to
upgradepkg to.
Comments (and suggestions for improving it) are welcome.
