+- r2ch.py counts the number outcome of a channel change as a function of
+  the channels involved.
+
+  ./r1.pl log | ./r2ch.py
+
+  Show for each channel we depart from, channel we enter, and distance of
+  the change the following numbers:
+
+  - channel number or distance
+  - total number of associations
+  - associations to the correct channel
+  - associations to the channel we departed from
+  - associations to a different channel
+  - number of times communication could not be reestablished
+
+  The option -p changes the last four numbers to percents of associations.
+
+- r3ch.plot plots the output of r2ch.py into a PNG file:
+
+  ./r1.pl log | ./r2ch.py -p | ./r3ch-plot DIST
+
+  plots the distribution by association type as a function of the hopping
+  distance. The other results are accessed with the keys FROM and TO.
+
+  By default, the PNG file is displayed with ImageMagick and then discarded.
+  With the option -f, it is written to a file with the name <key>.png or,
+  if the input comes from a file, <name>-<key>.png
