[IPython-dev] IPython 0.11.rc1 as a built-in shell for a GUI

[Hugo Gagnon]

Hi Brian,

No worries, I contacted MinRK personally and he amiably guided me
through the port. Everything (almost) work fine now. As it turned out
all I had to do is to use TerminalInteractiveShell and mimic what was in
the interact method.

Thank you all for your support,
