Interesting.  

I just started digging into wx.c to see if I could start envisioning a path
forward for a complete rewrite --- I'm thinking that each type of station
can set a flag for what kind of data it's actually providing, and higher-level
code can fill in the missing stuff if (and only if) necessary, rather than
each case statement having duplicated (!) code for handling things like
wind chill and this rain handling stuff.

Lo and behold, the first thing I saw was that there is NO code to handle
rain from Dallas One-Wire.  There is the following comment in its place:


// Rain:  I don't have a rain gauge, and I couldn't tell from the
// "OWW" docs exactly which of the four rain fields did what.  If
// someone can help me with that I'll add rain gauge code for the
// Dallas One-Wire.
                        
Sigh.
