Diplomacy PBEM

Order Syntax

The format of your diplomacy orders depends on the phase of the game:
Movement, Retreats or Adjustments.  Multiple orders can be entered on 
one line by separating them with commas or semicolons.

Movement orders:

(type) (s_prov) (holds)
(type) (s-prov) (moves)   (d-prov)
(type) (s-prov) (moves)   (c-prov) (moves) (c-prov) ... (moves) (d-prov)
(type) (s-prov) (support) (type)   (s-prov) 
(type) (s-prov) (support) (type)   (s-prov) (moves) (d-prov)
(type) (s-prov) (convoy)  (type)   (s-prov) (moves) (d-prov)

Retreat orders:

(type) (s-prov) (moves)   (d-prov)
(type) (s-prov) (disband)

Adjustment orders:

(build)  (type) (s-prov)
(remove) (type) (s-prov)

Where:

(type)    = "army", "a", "fleet", "f" or (empty).
(s-prov)  = Source province.
(d-prov)  = Destination province.
(c-prov)  = Intermediate water province in a convoy route.
(power)   = Power name or abbreviation of two or more characters.
(holds)   = "h", "hold", "holds", "stand", "stands".
(moves)   = "-", "-)", "m", "move", "moves", "move to", "moves to".
(support) = "s", "support", "supports".
(convoy)  = "c", "convoy", "convoys".
(disband) = "d", "disband".
(build)   = "b", "build" or (empty).
(remove)  = "r", "remove", "d", "disband" or (empty).

Province names can be abbreviated or can be spelled out.  Coasts can be
specified by following the province name with one of:

(coast)   = "/nc", "(nc)", "/north coast", "(north coast)"

or appropriate other directions instead of 'north'.

If a coast is not indicated, one will be chosen randomly.
