-copy this into any subdirectory of pypy from which scripts need
-to be run, typically all of the test subdirs.
-The idea is that any such script simply issues
-
- import autopath
-
-and this will make sure that the parent directory containing "pypy"
-is in sys.path.
-
-If you modify the master "autopath.py" version (in pypy/tool/autopath.py)
-you can directly run it which will copy itself on all autopath.py files
-it finds under the pypy root directory.
-
-This module always provides these attributes:
-
- pypydir pypy root directory path
- this_dir directory where this autopath.py resides
