+If you don't specify the amount of capital you have available to
+invest in the voyage, the trading plan will assume that your capital
+is unlimited.  If you specify an amount in PoE here, the trading plan
+will never require you to spend more than that amount on commodities.

+The trading plan does not take into account accumulated profits from
+each leg of the journey when applying the available capital
+constraint.  For example, if you specify a journey from A to B to C
+and a capital limit of 10000 PoE, the trading plan will not tell you
+to buy 1000 peas at A for 10 PoE each, sail them to B and sell all of
+them for 20 PoE each, and then buy 2000 beans at B for 10 PoE each and
+sail them to C to sell for 20 PoE each even if such a trade would in
+fact be possible.  In practice this is unlikely to be a problem!
