"""HOOMD-blue is a general-purpose particle simulation toolkit. It scales
from a single CPU core to thousands of GPUs.
You define particle initial conditions and interactions in a high-level
python script. Then tell HOOMD-blue how you want to execute the job and it
takes care of the rest. Python job scripts give you unlimited flexibility
to create custom initialization routines, control simulation parameters,
and perform in situ analysis."""
