You can patch it (Python / setuptools / whatever), but you don't
necessarily have to, as most Python objects are mutable, including
functions / methods, i.e., you can overwrite them... :-)
{{{
In [1]: import distutils.file_util
In [2]: def foo(s,t): print "Hello"
...:
In [3]: distutils.file_util.copy_file=foo
In [4]: distutils.file_util.copy_file("bar","baz")
Hello
}}}
And you could e.g. do so in an spkg's `setup.py`, to use some alternate
implementation (provided elsewhere).
