+
+        Inputs:
+
+         - *vars: one or more variables from the caller's namespace to be put
+         into the interactive IPython namespace.  The arguments can be given
+         in one of two forms, but ALL arguments must follow the same
+         convention (the first is checked and the rest are assumed to follow
+         it):
+         
+           a) All strings, naming variables in the caller.  These names are
+           evaluated in the caller's frame and put in, with the same name, in
+           the IPython namespace.
+
+           b) Pairs of (name, value), where the name is a string (a valid
+           python identifier).  In this case, the value is put into the
+           IPython namespace labeled by the given name.  This allows you to
+           rename your local variables so they don't collide with other names
+           you may already be using globally, or elsewhere and which you also
+           want to propagate.
+
+
+        This utility routine is meant to ease interactive debugging work,
+        where you want to easily propagate some internal variable in your code
+        up to the interactive namespace for further exploration.
+
+        When you run code via %run, globals in your script become visible at
+        the interactive prompt, but this doesn't happen for locals inside your
+        own functions and methods.  Yet when debugging, it is common to want
+        to explore some internal variables further at the interactive propmt.
+
+        Examples:
+
+        To use this, you first must obtain a handle on the ipython object as
+        indicated above, via:
+
+        import IPython.ipapi
+        ip = IPython.ipapi.get()
+
+        Once this is done, inside a routine foo() where you want to expose
+        variables x and y, you do the following:
+
+        def foo():
+            ...
+            x = your_computation()
+            y = something_else()
+            
+            # This pushes x and y to the interactive prompt immediately, even
+            # if this routine crashes on the next line after:
+            ip.to_user_ns('x','y')
+            ...
+            # return
+
+        The following example shows you how to rename variables to avoid
+        clashes:
+
+        def bar():
+            ...
+            x,y,z,w = foo()
+            
+            # Push these variables with different names, so they don't
+            # overwrite x and y from before
+            ip.to_user_ns(('x1',x),('y1',y),('z1',z),('w1',w))
+            # which is more conveniently written as:
+            ip.to_user_ns(*zip(('x1','y1','z1','w1'),(x,y,z,w)))
+            
+            ...
