Client Scripting :

     CSL (C Scripting language) scripting is functional ( GTK -gui

        o Units (exposed most functions  & all enum as constants)
        o Terrain (exposed most functions & all enum as constants)
        o Map (exposed most functions & all enum as constants)
        o Client- Server API (exposed most function needed by the client
          (control.c) )
        o Cities (Must still implement)
        o Diplomacy (Must still implement)
        o Player (Must still implement)

     Javascript work in progress (GTK-gui only):
        o Redesigning the interface. (Changing from global methos/functions
          to exposing Javascript classes ( Unit,City,Map,Player ) and
          assotiating the client-server requests with each Class

     Guile scripting : (GTK-gui only)
        o just started with design.

     AI Entities:
             Implementing  Client Side only (for now):
        o Economic Entity : Still needs implementation (This entity Controls
          Production in cities so that Military entities can make requests
          for New Units / Upgrades etc,  Requests will be priotitised ,
          queued and distibuted to aprppriate cities under its control.)
        o Defensive Military Entity : Work in progress (Very Simple Patrol
          near all Cities/  If the Borders (currenlty discused in list) are
          implemeted it would make it very easy to patrol around the border/
          Needs lots of work, Needs to know about deplomisy so it does not
          destroy allied units etc..).
        o Agresive Military Entity : Have not started with this,  But this
          Entity will have to know something of logistics in order to make a
          succesfull Invasions, Also needs to know about Diplomisy So it dont
          invade your allies, Needs the Econimc Entity to replenish lost
          units /cruise missiles etc... and place conquired cities under the
          control on the Economic Entity,

The scripting interface is very simple so other xxx-gui can easily be

   * Needs to add a "Add to script" command in he Orders menu
   * Needs to have a "File selection Popup/Dialog" screen to select the

I did  post a Patch with the CSL Scripting code on  freeciv-dev  "22 Nov
2001":   Look in the mailing list archive  (It seems to be down at the
