usage_description="
Automates Mouse Clicks to automate tedious UI actions

Performs N mouse clicks at the sequence of X,Y coordinates given or the current mouse location if no coordinates

Sleeps for \$SLEEP_SECS (default: 1) between clicks to allow UIs to update and perform the next click

Starts clicking after \$START_DELAYS seconds (default: 5) to give time to alt-tab back to your UI application and position the cursor

If given num is negative, will run indefinitely until Control-C'd
