-The method of choice to conduct tests is to run the file
-``theano-nose``. In a regular Theano installation, the latter will be
-on the operating system's path and directly accessible from any
-folder. Otherwise, it can be accessed in the ``Theano/bin``
-folder. The following command lines may be used for the corresponding
-purposes:
-
-* ``theano-nose --theano``: Run every test found in Theano's path.
-
-* ``theano-nose folder_name``: Run every test found in the folder *folder_name*.
-
-* ``theano-nose test_file.py``: Run every test found in the file *test_file.py*.
-
-The following are particularly useful for development purposes since
-they call for particular classes or even for particular tests:
-
-* ``theano-nose test_file.py:TestDoubleRop``: Run every test found inside the
-  class *TestDoubleRop*.
-
-* ``theano-nose test_file.py:TestDoubleRop.test_double_op``: Run only the test
-  *test_double_op* in the class *TestDoubleRop*.
