slop - 7.6-5 main

slop (Select Operation) is an application that queries for a
selection from the user and prints the region to stdout. It grabs the
mouse and turns it into a crosshair, lets the user click and drag to
make a selection (or click on a window) while drawing a pretty box
around it, then finally prints the selection's dimensions to stdout.
.
