descr = """Python Control Systems Library

The Python Control Systems Library, python-control,

is a python module that implements basic operations

for analysis and design of feedback control systems.

Features:

Linear input/output systems in state space and frequency domain

Block diagram algebra: serial, parallel and feedback interconnections

Time response: initial, step, impulse

Frequency response: Bode and Nyquist plots

Control analysis: stability, reachability, observability, stability margins

Control design: eigenvalue placement, linear quadratic regulator

Estimator design: linear quadratic estimator (Kalman filter)
