There was a proposed patch to do that, rejected, basically because doing so could potentially slow down the interpreter start up; see http://bugs.python.org/issue1174614; PEP 370 http://www.python.org/dev/peps/pep-0370/ if approved, may be useful to you. Note that you can always do the processing in sitecustomize.py, calling site.addsitedir for all entries in sys.path until no more entries are added. > This really smells like a bug in either the code or the docs.

Looks like the docs are wrong; the code in site.py, its docstring, and the above quoted docs are slightly different. -- Gabriel Genellina -- http://mail.python.org/mailman/listinfo/python-list
