[freeciv-ai] Question on find_boat

[Jordi Negrevernis i Font <jorneg@xxxxxxxxxxx>]

   Hi!

   I'm programming the code required to transport an army ( or part ) 
from a continent to another to attack a city. I'm having difficulties in 
finding the right way to use find_boat, as done in settlers.c. The ships 
full of troups flip-flop going out of the city and entering afterwards.
   I looked to the code of that function and it seems that is not 
checked if someone is allready using that ship!!!
   Which is the way to use boats with no passengers?

   Thanks
