[Insight-users] ITK Python Wrapping Examples

[Hua Qian]

Hi Luis,

I rebuilt ITK on another machine (Redhat 8.0) with the
same CVS checkout. This time, all the python examples
I tested ran nicely! The only change I made was to
put CableSwig checkout in the Utilities directory.
In my previous build (on a Mandrake), I put CableSwig
in parallel with Insight. I am doing a fresh build on my
Mandrake box right now and I'll let you know how it goes
when the build completed. It will take a few hours.

Regards,

Hua
