nvi-doc binary package in Ubuntu Trusty amd64

 Vi is the original screen based text editor for Unix systems.
 It is considered the standard text editor, and is available on
 almost all Unix systems.
 .
 Nvi is intended as a "bug-for-bug compatible" clone of the original
 BSD vi editor. As such, it doesn't have a lot of snazzy features as do
 some of the other vi clones such as elvis and vim. However, if all
 you want is vi, this is the one to get.
 .
 This package contains the tutorials and the reference manual.
