* Delete removes the selection for the current image (this is then
also not printed out at the end).
* Space bar resizes the image if the window was resized.
+* Tab switches the color of the selection box between the two colors
+ defined at the top of `croptool.c` (SELECTION_COLOR1, SELECTION_COLOR2).
Note that resizing the window currently does not resize the images.
It will only take effect if you move to another image or press

If you want to, you can edit a few things at the top of `bookcrop.c`.
COLLISION_PADDING is the number of pixels to check for collision if
an edge or corner is clicked.
-SELECTION_COLOR is the color the selection box is drawn in.
+SELECTION_COLOR1 and SELECTION_COLOR2 are the two colors for the
+selection box that can be switched with tab.
If you want to change the command that is output, you can change
the function `print_cmd`. It just receives the filename, the coordinates
of the top left corner of the cropping box, and the width and height
