A context manager (Python 2.5+ only) for stepping into a directory and automatically coming back to the previous one. The original directory is returned. Usage is like this:
from __future__ import with_statement
# the above line is only needed for Python 2.5
from paver.easy import *
@task
def my_task():
with pushd('new/directory') as old_dir:
...do stuff...
