 If no changes are being made to the icons or stylesheets, you may want to ensure that the `dist` directory is assumed to be unchanged in git, no longer tracking changes to these files. You can turn tracking distribution files off with:
 
 ```bash
-python git.py --no-track-dist
+python vcs.py --no-track-dist
 ```
 
 To turn back on tracking, run:
 
 ```bash
-python git.py --track-dist
+python vcs.py --track-dist
