#-------------------------------------------------------------------------------
#  This system allows you to break the 4 team barrier setup by RPGMaker VX.  By
#  using this code, you can have 5, 6 or even 10 member parties.
#
#  This page of the code can enhance your project  to allow parties of over four
#  members.   The controls are  very simple.   To establish  a default number of
#  party members,  edit the PARTY SIZE value in the configuration section below.
#  If you wish to alter the party size limit while the game is running,  call on
#  the $game_party.party_size value  from a map event and change it there.  But,
#  remember that you'll need to run '$game_party.refresh' for the change to take
#  effect.
#------------------------------------------------------------------------------
#
