Interesting package. Congratulations on making milestone release

I installed it and on a first look I can't see it workflow. On web
portal I found tip to follow examples that come with this package, but
those aren't trivial at all; I mean lot of classes and functions comes
from nowhare and it's like no walkthrough provided

If I may explain myself, I got summer seminar assigment, starting from
shallow water eqs to derive eq of absolute vorticity for nondivergent
flow in linearized form using perturbation method. I've done it by
hand, but would like to understand the process with some of Python
packages if feasible, and as staring eqs are hyperbolic PDEs maybe I
could use this package although it uses different method for solving.
Is it good idea to try to use this package, and if answer is yes, can
you maybe provide some starting point for this simple task?


Thanks
