Well, curiosity got the better of me (and gone is my night of sleep).
And here is version 0.5 of the Kindle packager; almost fully rewritten.
*Can now create packages for the Kindle 2 International that will install properly, even without having installed the previous freekindle package.
For that use the -k2iex flag.
-k2i will still generate packages requiring the freekindle package to have been installed first.
I suspect that developers would use the -k2i for testing (with the freekindle package installed), and when they are 100% confident and ready for release, us the -k2iex.
*Do not leave junk behind (like .dat, .sig files etc)... We now only use temporary files that get automatically deleted...
All other packages (usbnetwork, screen saver hack, savory) got repackaged using -k2iex : so installation is now much easier.
And are available as always:
