+Tracer v0.8.2
+
+Etherdream DACs handler on network via Redis
+
+LICENCE : CC
+Sam Neurohack, pclf
+
+One tracer process is launched per requested laser by LJ. Lasers parameters in LJ.conf.
+Live I/O based on redis keys : inputs (Pointlists to draw,...) and outputs (DAC state, errors,..).
+Keys are mostly read and set at each main loop.
+
+* Redis keys reference *
+
+- Drawing things :
+
+/pl/Scene/lasernumber  [(x,y,color),(x1,y1,color),...]   The live list of drawn pygame points. Tracer continously ask redis for key /clientkey+lasernumber
+/resampler/lasernumber [(1.0,8), (0.25,3),(0.75,3),(1.0,10)] : a string for resampling rules.
+                            the first tuple (1.0,8) is for short line < 4000 in etherdream space
+                            (0.25,3),(0.75,3),(1.0,10) for long line > 4000
+                            i.e (0.25,3) means go at 25% position on the line, send 3 times this position to etherdream
+/clientkey              "/pl/SceneNumber/"              What Scene to retrieve from redis
+/EDH/lasernumber
+
+- Tracer control :
+
+/order                  0-8                     Set redis key with new value then issue the order number
+
+                        0 : Draw Normal point list
+                        1 : Get the new EDH          = reread redis key /EDH/lasernumber
+                        2 : Draw BLACK point list
+                        3 : Draw GRID point list
+                        4 : Resampler Change (longs and shorts lsteps)
+                        5 : Client Key Change        = reread redis key /clientkey
+                        6 : Max Intensity Change     = reread redis key /intensity
+                        7 : kpps change              = reread redis key /kpps
+                        8 : color balance change     = reread redis keys /red /green /blue
+
+
+- Managing Etherdream DACs :
+
+Discrete drawing values
+
+/kpps                   0-                DAC output speed to laser, then order 7. Depends of actual angle
+/intensity              0-255             Laser output power, then order 6 (for alignement,...)
+/red                    0-100             % of full red, then order 8
+/green                  0-100             % of full green, then order 8
+/blue                   0-100             % of full blue, then order 8
+
+DAC status report
+
+/lstt/lasernumber       etherdream last_status.playback_state  (0: idle   1: prepare   2: playing)
+/cap/lasernumber        number of empty points sent to fill etherdream buffer (up to 1799)
+/lack/lasernumber       "a": ACK   "F": Full  "I": invalid. 64 or 35 for no connection.

+Tracer v0.8.2
+
+Etherdream DACs handler on network via Redis
+
+LICENCE : CC
+Sam Neurohack, pclf
+
+Includes live conversion in etherdream coordinates, geometric corrections, color balance change, intensity limitation, grid display,...
+
+One tracer process is launched per requested laser by LJ. Lasers parameters in LJ.conf.
+Live I/O based on redis keys : inputs (Pointlists to draw,...) and outputs (DAC state, errors,..).
+Keys are mostly read and set at each main loop.
+This tracer include an enhanced version (support for several lasers) of the etherdream python library from j4cDAC.
+
+
+* Redis keys reference *
+
+- Drawing things :
+
+/pl/Scene/lasernumber  [(x,y,color),(x1,y1,color),...]   The live list of drawn pygame points. Tracer continously ask redis for key /clientkey+lasernumber
+/resampler/lasernumber [(1.0,8), (0.25,3),(0.75,3),(1.0,10)] : a string for resampling rules.
+							the first tuple (1.0,8) is for short line < 4000 in etherdream space
+							(0.25,3),(0.75,3),(1.0,10) for long line > 4000
+							i.e (0.25,3) means go at 25% position on the line, send 3 times this position to etherdream
+/clientkey              "/pl/SceneNumber/"              What Scene to retrieve from redis
+/EDH/lasernumber
+
+- Tracer control :
+
+/order                  0-8                     Set redis key with new value then issue the order number
+
+						0 : Draw Normal point list
+						1 : Get the new EDH          = reread redis key /EDH/lasernumber
+						2 : Draw BLACK point list
+						3 : Draw GRID point list
+						4 : Resampler Change (longs and shorts lsteps)
+						5 : Client Key Change        = reread redis key /clientkey
+						6 : Max Intensity Change     = reread redis key /intensity
+						7 : kpps change              = reread redis key /kpps
+						8 : color balance change     = reread redis keys /red /green /blue
+
+
+- Managing Etherdream DACs :
+
+Discrete drawing values
+
+/kpps                   0-                DAC output speed to laser, then order 7. Depends of actual angle
+/intensity              0-255             Laser output power, then order 6 (for alignement,...)
+/red                    0-100             % of full red, then order 8
+/green                  0-100             % of full green, then order 8
+/blue                   0-100             % of full blue, then order 8
+
+DAC status report
+
+/lstt/lasernumber       etherdream last_status.playback_state  (0: idle   1: prepare   2: playing)
+/cap/lasernumber        number of empty points sent to fill etherdream buffer (up to 1799)
+/lack/lasernumber       "a": ACK   "F": Full  "I": invalid. 64 or 35 for no connection.
