Thank You Paul - I am very interested.
In between drinking coffee and smashing coffee cups, I actually visited your
site and my
impression was: wow, If I could only take the time instead of struggling with
this
'almost there' re thing!
I am not that good at it actually, but working hard, not worrying about the
cups to much...
I will now revisit pyparsing and learn!
I cheated a bit on you and read this: http://www.oreillynet.com/pub/au/2557.
I live in a little danish town, Svendborg, nice by the sea and all.
I learned steel construction in the 80's at the local shipyard,
(now closed), much later (96-98) I received a very short education in
IT-skills on a business school in Odense, the nearest city.
I spent the years 98-05 working for Maersk Data, later IBM.
From 05 and onwards independent.
Struggling hard to keep orders at a bare minimum,
I spend some of my spare time working with the elderly, and some of it
programming python for different purposes at home, and some of it playing
in the band: http://myspace.com/dementedk, and some of it combining the two.
So now You know more or less the same about me as I know about You.
Jorgen
