Ubuntu installer overview

Ubuntu and its various flavours (Kubuntu, Edubuntu, Xubuntu) have two installers. One is a modified version of the Debian installer, known as "d-i", and is written in POSIX shell script and C. The other, Ubiquity, is used on our live CD (or "desktop CD"), features a from-scratch user interface design, and has a good deal of front-end code written in Python, but behind the scenes still uses d-i code for many back-end tasks where it's important that we don't end up maintaining two implementations.
