[wingide-users] Conditionally importing modules when Wing is not active/running

[Tony Cappellini]

Hello,

I would like to leave

try:
   import wingdbstub:
except ImportError:
   pass

in my project files, but also want to conditionally import psyco when
I'm not running Wing.

WINGDB_ACTIVE is always set in the environment, whenever wingdbstub is
imported, even if Wing is not running.

Is there another Wing environment variable I can use reliably to
detect when Wing is not really running?
