# usage: mtt <sys> cxxsim view
# example:
# mtt copy MotorGenerator && cd MotorGenerator && mtt MotorGenerator cxxsim view
# cxxsim creates a very simple C++ simulation without using Reduce
# it doesn't use MTT's normal .txt files so the resultant .cc must be edited
# manually to alter parameter, input and logic values
# a more intelligent version would just do ese_r2cc to create <sys>_ese.cc
# this could then be embedded into MTT's normal code like <sys>_ode.cc
# maybe another day ...
