When I first used Wine to try to install Windows software on my Linux machine, I found it less than user-friendly. Fortunately there was an application called WineTools to help smooth out the process. WineTools helps you download essential Windows add-ons like DLLs and Internet Explorer -- a necessity for most users, since a great many third-party Windows apps rely on IE's low-level system integrating to implement essential services. But WineTools has not aged well, and using it increasingly causes problems for other Wine applications. Luckily a new project called Wine Doors is picking up where WineTools left off.

Just about any distro these days installs nicely to the hard drive. What can sometimes happen is that the system breaks when packages are added to the collection which the distro provides by default. And when packages are removed from the provided collection, no-longer-necessary «helper» programs may be left behind, or «orphaned». Work-arounds include sticking with packages which the distro itself supplies in its repository. In the world of Debian, some distros may «tweak» purely-Debian packages to fit better with the overall distro. It is in this context that the question presents itself: is the Debian «Aptitude» tool something which a Debian-based distro might want to use when it builds its version on the shop floor? And might even a certain type of newbie want eventually to «graduate» to Debian in a more nearly perfectly «pure» form and use Aptitude like this? Has Aptitude not been widely discussed because it's not yet in widespread use? ‑‑ This essay seeks to raise these questions from the perspective of a total newbie.
