concerning all your mails about embedding ROOT.
- the idea is to only once create an TApplication or TRint object.
Since the ctor removes the TApplication specific arguments from the
argv the second call wil not work as expected (unless you first
save the argv vector). Anyway, not much will be gained from creating
and deleting multiple times the TApplication object.
- I agree however that only when entering Run() stty options should be set
and restored when exiting (currently this happens in the ctor).
I'll fix this.
- Also I'll give you access to the array of batch files to be executed
when entering Run().
These new features should be available in the next week version.
Cheers, Fons.
