Not correct ReStructured Text list format should be:

    This function can implement:

    * Linear convolutional layer
    * Rectifier convolutional layer
    * Sigmoid convolutional layer
    * Tanh convolutional layer

    based on the nonlinearity argument that it gets.

The whitespace is important: the list entires should not be indented, and there needs to be a blank line above and below the list. Otherwise it won't get formatted right on the documentation website.
