#DESCRIPTION

  This file creates a vimball of the .vim personalization files specified in
  the files.txt file.  Assumes GNU make 3.8.1 and a GNU tar 2.8.3 or later.

#INSTRUCTIONS

  Use make with one of the following phony targets

  - *vimball* creates the vimball for installation

  - *update* fetches updates from GitHub. Assumes you have a git repository
    and git installed.

  - *fetch* copies your personal changes from your installation to this
    directory. You may then add, commit and submit a merge request to me for
    consideration/inclusion. Please describe what your changes accomplish and
    why they are important to you. Or just keep them in your own special branch.
