This is a really cool tip I stumbled onto while working with some of the packages on my team.  A couple months back I was editing a spec file and accidentally mistyped the name of the spec file.  Much to my surprise most of the file was completely missing.  After several :q! I finally realized that vi has a skeleton spec file that gets generated when edit a *.spec file that doesn’t exist yet.

So, for example if you typed:

 vi mypackage.spec

you would get:

#
# This file and all modifications and additions to the pristine
# package are under the same license as the package itself.
#

# norootforbuild
