+
+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.
