-- this script is meant to be used when the output for the command
-- doesn't have more than a screenful of lines (approx 30-35 lines).
-- eg. tail, head, grep, ps ... etc.
--
-- CAUTION
-- DO NOT use this to execute something like xterm, vi or anything
-- similar (use the given key-bindings like MOD2..F2/F3/F4/F5 for those).

-- do let me know if this doesn't work for someone.
