version in app.yaml ignored

[GoogleCodeExporter]

I don't know if this is a bug or not implemented yet, but the version in 
app.yaml is ignored and the server name always set to "default". This does also 
prevent running multiple versions simultaneously.

../../dev_appserver.py 1/app.yaml 2/app.yaml

google.appengine.tools.devappserver2.errors.InvalidAppConfigError: Duplicate 
server: default

Could you explain your use case for having multiple simultaneous versions?

I put tasks on a different version named "task" to separate incoming requests 
and frequent but short background tasks, like reading a value from a website 
and updating the corresponding db entry. I also send each mail as a separate 
task on version "mail". This is mostly to keep separate logs and not spam the 
default version.

Another bonus is separate charts in the dashboard. I considered this common 
practice actually.
