# the script; they are necessary dependencies

#
# Description: This script uses [stow] to create the appropriate symlinks
# If you decide there were some things that you don't want/need that were
# linked, you can delete it from your HOME directory ..
#   TIP: view symlinks with `ls -la` in your HOME directory, then proceed to
#   remove the link: `rm <link>`
