VIM (VIsual editor iMproved) is an updated and improved version of the vi
editor. Vi was the first real screen-based editor for UNIX, and is still
very popular. VIM improves on vi by adding new features: multiple windows,
multi-level undo, block highlighting and more. The vim-minimal package
includes a minimal version of VIM, which is installed into /bin/vi for use
when only the root partition is present.
