GiftWrap helps you with the management side of packaging. It allows you to create and update Ubuntu packages, upload to a PPA and more. It helps you in creating Ubuntu .deb packages by guiding through the process with minimal fuss and maximum automation. GiftWrap also aims to help you in creating high-quality packages by helping you fill in as most of the package meta-information as possible - either by automatically detecting or explaining the options in an easy to understand manner.
Last but not least, GiftWrap's interface aims to be clean and easy to understand (HIG 2.2 compliant) and development-friendly with well-documented code (to be done in the near future) and roadmap.
