+-- To use this module add:
+--   local scratchdrop = require("scratchdrop")
+-- to the top of your rc.lua, and call it from a keybinding:
+--   scratchdrop(prog, vert, horiz, width, height, sticky, screen)
+--
+-- Parameters:
+--   prog   - Program to run; "urxvt", "gmrun", "thunderbird"
+--   vert   - Vertical; "bottom", "center" or "top" (default)
+--   horiz  - Horizontal; "left", "right" or "center" (default)
+--   width  - Width in absolute pixels, or width percentage
+--            when <= 1 (1 (100% of the screen) by default)
+--   height - Height in absolute pixels, or height percentage
+--            when <= 1 (0.25 (25% of the screen) by default)
+--   sticky - Visible on all tags, false by default
+--   screen - Screen (optional), mouse.screen by default
