# 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 full-size figure
#    called `figure_name.png` in the `full_size_figures` directory.
# A corresponding smaller resized figure is automagically created
# in the `images/figures` directory. The idea is to keep the full-size figures
# in case they're ever needed, but to resize them so they're not too big
# for inclusion in the document.
# The method is to look for the most recently modified PNG file on the desktop
# and move it (while renaming it) to the `full_size_figures` directory. Then
# a normal-size figure is generated using the `make_figures` script.
