+      [internal] This task will set up a symlink to the shared directory \
+      for the assets directory. Assets are shared across deploys to avoid \
+      mid-deploy mismatches between old application html asking for assets \
+      and getting a 404 file not found error. The assets cache is shared \
+      for efficiency. If you cutomize the assets path prefix, override the \
+      :assets_prefix variable to match.
