Oh my @#*%, where did ipapi go?

Originally, this module was designed to be a public api for IPython. It is
|
|
|
now deprecated and replaced by :class:`IPython.core.Interactive` shell.
|
|
|
Almost all of the methods that were here are now there, but possibly renamed.
|
|
|
|
|
|
During our transition, we will keep this simple module with its :func:`get`
|
|
|
function. It too will eventually go away when the new component querying
|
|
|
interface is fully used.
