This class can be used as a context manager or as an OO representation of a
temporary directory.
Attributes:
path
Location to the created temporary directory or None
delete
Whether the directory should be deleted when exiting
(when used as a contextmanager)
Methods:
create()
Creates a temporary directory and stores its path in the path
attribute.
cleanup()
Deletes the temporary directory and sets path attribute to None
When used as a context manager, a temporary directory is created on
entering the context and, if the delete attribute is True, on exiting the
context the created directory is deleted.

valid package names (for both Python and pip definitions of
package).
