When I got my Vantage Pro Weather Station, I wrote Python code to
connect it to Mysql.  I need a means to pass a little data between
different programs where the consumer wants data that may have been
in use hours earlier.  I started with different file names each
with a line of data, but then it dawned on me a ver small subset
of the Windows registry made sense.  So the weather database grew
a new table and can be accessed via Python code or a Python command
line.

It even has import/export methods that use colon separated ascii files.  XML?
Not worth it, but easy to do I'm sure.  It's worked for so long I never
remember where the source is.  It's been almost four years since I modified
it.

DIE is too strong a word.  Replace, simplify, constrain are far more
useful.
