# To update to the newest version of SWORD do the following:
# * Scroll down to the line where the "rev" is listed
# * Update that value to match the latest revision of SWORD's SVN trunk
# * Comment out the hash line below that
# * Run a `nix build` on the current target
# * When you receive an error about the hash mismatch, copy the correct value
#   and paste it into the hash as the new value, then uncomment the hash
# * Run the build again. It won't need to re-fetch the sources, it will only
#   execute the build
