+#          FILE: setup.sh
+#         USAGE: ./setup.sh 
+#   DESCRIPTION: after pulling/cloning dotfiles repo, this script will check/create
+#                symlinks for for dotfiles.  It checks for the presence of installed
+#                software (i.e. won't symlink a dotfile for applications that aren't
+#                installed) and will remove links for applications that are no longer
+#                installed.  Safe to run after every git pull
+#       OPTIONS: 
+#  REQUIREMENTS: This script replies on the 'command' command.  Basically, it will run
+#                `command -v <dotfile>` and if there is no output, it assumes the app
+#                isn't installed.  So this won't work for apps that aren't in your $PATH
