7b69e630d237 PEP 3147 Barry Warsaw <barry@python.org> parents: 60022 diff changeset	47 number also includes a new "magic tag", i.e. a human readable string used
7b69e630d237 PEP 3147 Barry Warsaw <barry@python.org> parents: 60022 diff changeset	48 to represent the magic number in __pycache__ directories. When you change
7b69e630d237 PEP 3147 Barry Warsaw <barry@python.org> parents: 60022 diff changeset	49 the magic number, you must also set a new unique magic tag. Generally this
