# Renames a screenshot.
# This is intended for use with Shift-Cmd-4 on Mac OS X.
# 1. Use Shift-Cmd-4 to take a screenshot
# 2. Run `rename_screenshot figure_name` to create a figure
# called `figure_name.png` in the `images/figures/` directory.
# The method is to look for the most recently modified PNG file on the desktop
# and move it (while renaming it) to the `images/figures` directory.
