The "~" operator in the version is very helpful: 1.2.3-1~foo is > less than 1.2.3-1.

Also see the "prevu" tool in the Ubuntu repos: > https://wiki.ubuntu.com/Prevu > > It's designed to automate this process in one fell swoop, such as "prevu > bash" which goes to LaunchPad and automatically grabs the newest Jaunty > sources for bash, and builds it.

Prevu also functions just like > the "pdebuild" command when you run it with no arguments within a Debian > source directory so you can use it as a replacement for your pbuilder setup. > > Ok, thanks. Is it just like a update process?
apt-get source <pakket> wget <newer version.tar.gz> mv hello-2.3.tar.gz hello_2.3.orig.tar.gz tar xfz hello_2.3.orig.tar.gz cd hello_2.3/ zcat ../hello_2.2-2.diff.gz | patch -p1 dch -i How do I get the Jaunty package in a Intrepid environment? Or the source?
