+char examplestring[] = "\n\
+\n\
+    Welcome to the NILM Ethstream examples.\n\
+\n\
+For the most part, typing \"ethstream\" by itself will sample the first\n\
+two channels at 8 kHz on 10V range.  Press CTRL-C to terminate sampling.\n\
+\n\
+If you want current measurements on the first two phases of NILM\n\
+with default sample rate of 8 kHz and 10V range:\n\
+\n\
+   ethstream -C 0,3\n\
+\n\
+The device is configured so that channels 0 through 2 are currents for\n\
+the three phases and channels 3-5 are for voltages of the three phases.\n\
+The current channels sample voltages that will depend on the DIP switch\n\
+settings in the NILM box.  The DIP switch positions allow you to convert\n\
+ethstream's readings to true current readings.\n\
+\n\
+If you want only currents at 16 kHz and 10V range:\n\
+\n\
+    ethstream -n 3 -r 16000\n\
+\n\
+The -n option samples a number of channels starting at 0. The rate can be\n\
+at least 16000 if 12 channels are sampled , but it can do more if\n\
+fewer channels are sampled.  The limiting factor is the highest channel\n\
+sampled.  Sampling just the top channel (11) is as bad as sampling\n\
+all 12 at once.\n\
+Ethstream will warn if you approach the limits of the NerdJack with the\n\
+given sampled channels.  Sampling outside the range of the NerdJack might\n\
+result in corrupt data or crashing of the device.  There will be no\n\
+permanent damage to NILM or NerdJack, but be aware of the possibility of\n\
+data corruption.\n\
+\n\
+If you need a higher accuracy but lower range measurement on the voltages:\n\
+\n\
+    ethstream -R 5,10 -C 3,4,5\n\
+\n\
+The two numbers to the R command set the range to either 5V or 10V. Above,\n\
+we are setting channels 0-5 to 5 V range and channels 6-11 to 10 V range.\n\
+Channels 6-11 are unconnected, but they can have range set independently.\n\
+\n\
+All of the above examples output a digital number from 0 to 65535 with\n\
+65535 representing the highest range (5V or 10V).  0 represents the most\n\
+negative range (-5V or -10V).  If you want conversion\n\
+to volts for all six voltages and currents:\n\
+\n\
+    ethstream -c -C 0,3,1,4,2,5\n\
+\n\
+The channels will be output in the order given in the C command.  This\n\
+command will group the current and voltage data by phase.\n\
+\n\
+If you are supplying data from ethstream to another program, you might\n\
+want to dump its output to a file and terminate after a certain number of\n\
+samples:\n\
+\n\
+    ethstream -n 6 -r 8000 - l 16000 > outfile.dat\n\
+\n\
+This will take 16000 samples at 8 kHz (2 seconds of acquisition) of all\n\
+channels and write the data to outfile.dat.  This can be directly read\n\
+by a package like MATLAB.\n\
+\n\
+If there are multiple NerdJacks or you have changed the TCP/IP settings\n\
+from default, you might have to specify which one you want to talk to:\n\
+\n\
+    ethstream -a 192.168.1.210\n\
+\n\
+This will sample two channels at 8 kHz from the NerdJack at 192.168.1.210.\n\
+This is the default \"1\" setting on the NerdJack.  If no address is\n\
+specified, ethstream connects first to 192.168.1.209.  It then tries\n\
+to autodetect the NerdJack.  This should find the device if you are on\n\
+the same network, but it will get confused if there are multiple NerdJacks\n\
+on the network.\n\
+\n\
+Labjack only Timer modes are also avaliable.  Read the Labjack UE9 Users Guide\n\
+for more information.  Upto 6 timers of various modes can be specified,\n\
+they occur on FIO0-FIO5 which are on channels 200-205 respectively in order\n\
+of specification.  For 32 bit timer modes, the MSW should be read from\n\
+channel 224 imeadiately after the LSW is read from one the timer channel.\n\
+A clock frequency divisor is specified on a per device basis.  For example:\n\
+\n\
+    ethstream -t 4,12 -T 1 -C 200,224,201\n\
+\n\
+This will enable two timers with the fastest system clock divisor (48 MhZ/1)\n\
+and read the two 16 bit words for timer mode 4 and the single 16 bit word of\n\
+timer mode 12.  These three words will occupy their own columns in the output\n\
+stream.  Digital timer mode channels can be interspersed with analog inouts.\n\
+\n\
+Labjack only individual analog input channel gain set is also avaliable.\n\
+Gain 0 is default on labjack and corresponds to -5.18v to +5.07v.  Gain 1 is\n\
+is -0.01 to +5.07v.  Gain 2 is -0.01 to +2.53v.  Gain 4 is -0.01 to +1.26v.\n\
+Gain 8 is -0.01 to +0.62v.  Gains on the -g flag should be put in the desired\n\
+order corresponding to the channels as specified by the -C flag.  If there are\n\
+less gains specified than channels the remainder default to gain 0.  Extra gains\n\
+are ignored.  Gains can be specified for digital inputs or timer modes but they\n\
+are irrelevant.  A case where one should do this is if there are dital input\n\
+channels intersperced within analog input channels; this keeps the order matched\n\
+up so later analog input channels have the expected gain.\n\
+\n\
+    ethstream -t 4 -T 1 -C 0,1,200,224,2,3 -g 2,2,0,0,4,4 -c\n\
+\n\
+This will set channles 0,1 and 2,3 to gain 2,2 and 4,4, respectively and convert\n\
+the data to volts using the firmware stored factory calibrated data on the\n\
+labjack. The digital channels 200 and 224 will remain undisturbed as integers.\n\
