New features for debcheckout, … now with TopGit support!

Moving a git layout from debian-only to debian+upstream

… and live happily with git-buildpackage

Importing the package into Git

Cleaning up the SVN references

Setting things straight

Making ends meet

Turning `dpatch` files into feature branches

… and then Git let me down

The end

Introduction

Setting up the infrastructure

Importing the Debian package

The idea of feature branches

Setting up feature branches

Building the package (theory)

Building the package (practise)

Uploading a new Debian version

Hacking on the software

… when a new upstream version comes around

Creating and using a maintenance branch

Future directions

Wrapping up

debcheckout: some new bits

(Perl) Tip of the day: Switch.pm

Introducing debcheckout

RFC

Vcs-Cvs proposed convention

Tip of the day: Pod::Usage
