-Version History
+Finding your MesoWest `station` values
+--------------------------------------
+
+MesoWest has great documentation which can be found here:
+
+https://developers.synopticdata.com/mesonet/v2/getting-started/
+
+To complete the [station] configuration section for a MesoWest station,
+you must fill in the attributes of the MesoWest station ID from which
+you want to import data. Here are the steps to do that:
+
+1. Firstly, get set up with MesoWest's API by going to the above
+   'Getting Started' link. Once you're set up, you can copy a token from
+   the MesoWest web portal into your configuration file's `token` value.
+
+2. Next, you will want to find the Station ID for the MesoWest weather
+   station of interest and copy it to the `station_id` value.
+
+3. Finally, you must choose what data types you want to push into
+   InfoEx and compile them into a comma-separated list. MesoWest refers
+   to these as 'field names' or 'station variables' and a list is
+   available here:
+
+https://developers.synopticdata.com/about/station-variables/
+
+The MesoWest API supports on-the-fly unit conversion. If desired, that
+can be specified to infoex-autowx via the configuration option `units`.
+This can be either 'english' or 'metric', with 'english' meaning
+imperial units as used in the United States.
+
+A complete [station] section example:
+
+`[station]`  
+`type = mesowest`  
+`token = # token id copied from MesoWest web account #`  
+`station_id = OD110`  
+`desired_data = air_temp,snow_depth`  
+`units = english`
+
+indicates that I'd like to import "Temperature" and "Precipitation
+accumulated" from the MesoWest station at Santiam Pass, OR, into InfoEx,
+and that I want that data in imperial units.
+
+Custom weather station support
+------------------------------
+
+This program supports custom weather station data by allowing the user
+to specify the path to an external Python program. The external Python
+program should emit its data in the form expected by infoex-autowx.
+
+This is a powerful feature which enables the user to upload data from
+any source imaginable into InfoEx. Common examples are a local database
+or a remote web page which requires some custom parsing.
+
+Please see the program located at examples/custom-wx.example.py for a
+complete description of what's required.
+
+A note on supported measurements
+--------------------------------
+
+While this program supports several measurements, and will faithfully
+request all of the ones you specify (provided they're supported), the
+weather station may not record them. In this case, the data will simply
+be ignored (i.e. it will NOT log "0" when there's no measurement
+available).
+
+InfoEx provides a mechanism for inspecting your automated weather
+station data, so use that after setting this program up and compare it
+with the data you see in your web browser.
+
+Here's the list of measurements currently supported:
+
+**NRCS:**  
+PREC  
+TOBS  
+SNWD  
+PRES  
+RHUM  
+WSPD  
+WDIR  
+
+**MesoWest:**  
+precip\_accum  
+air\_temp  
+snow\_depth  
+pressure  
+relative\_humidity  
+wind\_speed  
+wind\_direction  
+wind\_gust  
+
+**Custom Wx program**  
+*infoex-autowx expects a custom Wx data provider to provide at least one
+of the following:*  
+precipitationGauge  
+tempPres  
+tempMaxHour  
+tempMinHour  
+hS  
+baro  
+rH  
+windSpeedNum  
+windDirectionNum

+- 3.0.0 (Nov 2020)
+
+  Implement Custom Wx data providers.
+
+  This release enables the user to write their own Python programs and
+  specify them to infoex-autowx as a data provider.
+
+  This in turn enables the user to pull data from e.g. a local database
+  or an HTML page and push it into their InfoEx auto station data,
+  limited only by the imagination.
+
+- 2.2.0 (Nov 2020)
+
+  Add support for Tmin/Tmax values (directly from MesoWest/NRCS).
+
+- 2.1.0 (Nov 2020)
+
+  Adjust precision of certain values before sending them to InfoEx.
+
+- 2.0.2 (Jul 2020)
+
+  Fix issues shown by pylint(1).
+
+- 2.0.1 (Jul 2020)
+
+  Major restructuring, but nothing which should impact the end user.
+
+  - Took the monolithic main () routine and broke it out into logical
+    components.
+  - Improved the names of variables.
+

 - 2.0.0 (Jul 2020)
 
   Implement MesoWest integration.
