Full descriptions and advice for all 18 commodities via the F8F8 Market screen. More variety, more realism, more trade possibilities, more moolah. MM makes an ideal pairing with Merchanter's Zeal (MM + MZ = $$$)";

/* ALL credit and homage to Spara for this code! The only things Reval changed were the content, and order of the items in the commodities array; also introduced conditional for the loop and a try catch() to reduce the logged errors. When, oh when will the devs fix this persistent Oolite BUG that even now, with version 1.91, forces workarounds and kludges like this? Shows how much _they_ care about Trading, eh? */
