[more about mocking stdio]

In addition to mocking stdio for testing, stdio_mgr can also be used to wrap functions that directly interact with stdio. Example:

>>> def embellish(func):
...     def func_wrapper(s):
...         from stdio_mgr import stdio_mgr
...
...         with stdio_mgr() as (i, o, e):
...             func(s)
...             content = o.getvalue()
...         newcontent = '*** ' + content.replace('\n', ' ***\n*** ')
...         newcontent = newcontent[:-5]
...         print(newcontent)
...     return func_wrapper

>>> @embellish
... def testfunc(s):
...     print(s)

>>> testfunc("""\
... Foo bar baz quux.
... Lorem ipsum dolor sit amet....""")
*** Foo bar baz quux. ***
*** Lorem ipsum dolor sit amet.... ***
