+# Launch a background job that deals with SASS/SCSS.
+#
+# If no arguments were given, then it will try to kill a previous instance
+# of the background job and launch another one. You can prevent the
+# re-launching by passing the "stop" argument. This way, this script will
+# efectively kill the currently running process and quit. Any other argument
+# will be ignored.
+#
+# Therefore, the usage of this script is as follows:
+#
+#   $ sass [stop]
+#
+
+
+##
+# Config values.
+#
+# NOTE: path values should *not* start and/or end with a slash.
+
+# The base directory.
+dir="$( cd "$( dirname "$0" )" && pwd )/.."

+# The absolute path to the directory where we can store temporary files. You
+# don't really want to use this default since it can easily clash with other
+# projects ;)
+tmp="/tmp"
+
+# The absolute path to the file that will store the PID of the currently
+# running background job.
+pidfile="$tmp/assets.pid"
+
+# The absolute path to the SASS log.
+csslog="$tmp/sass.log"
+
+# The absolute path of the directory containing the SASS files.
