GiftWrap helps you in creating Ubuntu .deb packages by guiding you through the process with minimal fuss and maximum automation. It also aims to help you in creating high-quality packages by helping you fill in as much of the package meta-information as possible, either by automatically detecting or explaining the options in an easy to understand manner. The 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 a roadmap.
debshare.create is a hackish script used for producing .debshare files, which are basically "self-executable", monolithic archives containing several .deb packages. A .debshare file is meant to install one (or more) applications that it contains, complete with all its dependencies. This facilitates easy sharing of applications across computers using a single file, as opposed to multiple .deb packages. This idea was originally meant for Ubuntu systems, but there should be no reason why it shouldn't work on other similar distributions. Technically, a .debshare file is a bash shell script with a binary payload (a tar archive with the .deb-s) appended to it.
