+Dug out the old AxiDraw to play around with
+<https://anvaka.github.io/city-roads/?q=rochester%2C%20ny&areaId=3600176069>.
+First problem: after installing the new AxiDraw version, connecting to the
+AxiDraw in Inkscape failed with `Failed to connect to AxiDraw`.  Sigh.  After
+much flailing, it turns out the problem was that something had `pip install`ed
+the `serial` module, which is some kind of serialization/deserialization
+library, and so `import serial` was importing that instead of pySerial, which is
+the serial port communication library that happens to use the module name
+`serial` too.  Ugh.  So `pip uninstall serial; pip install pySerial` fixed that.
+Then I tried to get the `Render > Hershey Text` thing working again, but it
+just… did nothing at all.  Looks like there's a *second* Hershey Text plugin,
+this time under the AxiDraw extension menu.  I guess I'm supposed to use that
+one now?  Who knows?
