+# Simple dotfile linking script.
+# Partly inspired by dotsync (https://github.com/dotphiles/dotsync).
+#
+# This script takes files in a version-controllable "dotdir" directory
+# and creates corresponding symlinks in the user's home directory.
+# Any existing files in the home directory are backed up before being
+# replaced with a symlink.
+
+# Root directory of dotfiles project
+BASEDIR=$(dirname "$(readlink -f "$0")")
+
+# Directory containing all dotfiles that will be linked to $HOMEDIR
+DOTDIR=${BASEDIR}/home
+
+# Directory into which files will be linked
+HOMEDIR=${HOME}
+
+# Directory into which any pre-existing dotfiles will be copied
+BACKUPDIR=${HOMEDIR}/.updatedots-backup
+
+# Dotfiles relative to $DOTDIR
+RDOTFILES=$(find ${DOTDIR} -type f -print | sed "s|^${DOTDIR}/||g")
+
+# Command used to create symbolic links
+LINK="ln --symbolic --relative"
+
+# Publish dotfiles to home directory, backing up any collisions
