"""Hook to allow user-specified customization code to run.

As a policy, Python doesn't run user-specified code on startup of

Python programs (interactive sessions execute the script specified in

the PYTHONSTARTUP environment variable if it exists).

However, some programs or sites may find it convenient to allow users

to have a standard customization file, which gets run when a program

requests it.  This module implements such a mechanism.  A program

that wishes to use the mechanism must execute the statement

    import user

The user module looks for a file .pythonrc.py in the user's home

directory and if it can be opened, execfile()s it in its own global

namespace.  Errors during this phase are not caught; that's up to the

program that imports the user module, if it wishes.

The user's .pythonrc.py could conceivably test for sys.version if it

wishes to do different things depending on the Python version.
