[mapserver-users] Problem with Python Mapscript / Projection(MS4W) + new question

[Fawcett, David]

Christian, 

My experience is that the Python MapScript 'community' is extremely
small.  I really don't think that there are many people using it.  If I
am wrong, please speak up users.  When I have posted questions to the
list, if I got any response, it was from developers like Sean or Howard.

My feeling is that if you want support, examples, etc. you should go
with php or maybe C# .NET MapScript.  I find this unfortunate because I
really like Python as a language and I write a lot of GIS related Python
code (ESRI and GDAL/OGR) as part of my job.  

David.

That's exactly it, it works, thank you David!

I'll take the occasion to ask about something that troubles me about
Python/Mapscript: what's the exact state of it, is it being actively
developed and used, and what's its exact relation with the other MS
components?

For a long time I wrote all my MS code in PHP, and I had no problem
finding reference and documentation, as it seems to be actively
maintained, and people are discussing techniques and issues everywhere.
But then I switched to Python/MS a couple of weeks ago, and I have a
hard time just finding a basic API guide for it, and I'm always
wondering if it's somewhat lagging behind its PHP brother, for some
reason.

Thank you for your kind help,

Christian
