+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.
