    To use Petra-M, use activartion command to setup envrioment
      > activate_twopi
    Then, you can start piScope
      TwoPi_xxx> piscope
    You can use twop command to update PetraM modules
      TwoPi_xxx> twopi update <module name>             # to check if update exists
      TwoPi_xxx> twopi update --install <module name>   # to check if update exists
      TwoPi_xxx> twopi update --install <module name>   # to check if update exists
