Description: Vi IMproved - enhanced vi editor
 Vim is an almost compatible version of the UNIX editor Vi.
 .
 Many new features have been added: multi level undo, syntax
 highlighting, command line history, on-line help, filename
 completion, block operations, folding, Unicode support, etc.
 .
 This package contains a version of vim compiled with a rather
 standard set of features.  This package does not provide a GUI
 version of Vim.  See the other vim-* packages if you need more
 (or less).
