selectable estimate...want to try estimate_last24h to see if it doesn't switch as often

 I started this under nvOC, but have since migrated my mining rig from nvOC
 to a standard Gentoo Linux setup.
 
+Usage
+=====
+
+./zpool-switch.py conf-file miner-file algo-map estimate_selection [algo]
+
+The switcher takes four parameters in normal operation:
+
+conf-file: general configuration (JSON)
+
+miner-file: miner configuration (JSON)
+
+algo-map: mapping from the algorithm labels zpool uses to the ones used in
+miner-file (JSON)
+
+estimate_selection: one of three values to determine switching behavior,
+based on the three estimates provided by zpool: estimate_current,
+estimate_last24h, actual_last24h.  estimate_current is likely to lead to
+more frequent switching than the other two.
+
+The optional fifth parameter lets you manually pick an algorithm for mining;
+this is useful for testing and benchmarking.
+
+zpool-switch configures the cards' fan and power settings, starts the miner
+in a screen session, and exits.  It should be called periodically (perhaps
+every 10-15 minutes); you could do this with a shell script, a cron job, or
+whatever other method you prefer.
