[Freeciv-Dev] BYO units

[Andy Black <ablack@xxxxxxxxxxxxxx>]

Hi

The folowing is a partial atempt to fit the build your own unit system into
the context of CivI/CivII/Freeciv/CTP.  The other parts are the attack,
defense and special.  These elements would include things like shield level
(wood/leather vs. bronze vs. Iron), weapons (spear vs. bow & arrow vs.
gun), and special (trade, diplomatic, teraforming, paradrop, carying units,
ignore walls, ignore ZOC, see subs, all roads, inc def, stealth?,
refuleing?).  Spliting the Civ 1/Civ 2/ freeciv units into their components
was difficult, but I think what I have described works.  Other chasis or
propulsion types could be created (ex: CH_HOVER for hovercraft,
CH_ROCKET:P_ICBM for intercontinental balistic missiles, CH_ROCKET:P_SAM
for 1-2 square range sam missiles)
