    (description
     "Vim is a highly configurable text editor built to enable efficient text
editing.  It is an improved version of the vi editor distributed with most UNIX
systems.

Vim is often called a \"programmer's editor,\" and so useful for programming
that many consider it an entire IDE.  It's not just for programmers, though.
Vim is perfect for all kinds of text editing, from composing email to editing
configuration files.")

from the @command{vi}-editor:
@enumerate
@item utf8 support
@item user mappings (almost like in @code{vi})
@item ranges in command
@item line commands
@item user defined commands (with support for ranges)
@item registers
@item operation undoing/redoing
@item fuse file systems support
@item trash
@item multiple files renaming
@item support of filename modifiers
@item colorschemes support
@item file name color according to file type
@item path specific colorscheme customization
@item bookmarks
@item operation backgrounding
@item customizable file viewers
@item handy @code{less}-like preview mode
@item filtering out and searching for files using regular expressions
@item one or two panes view
@end enumerate
With the package comes a plugin to use vifm as a vim file selector.")
