The script is Travian Add-in for the NPC merchant. The feautres list is:

• Extends the NPC merchant.
• Optimizes your resources for building as much troops as possible.
• Adds a link for the NPC merchant to the menu.
• Changes all your resources to another one with only two clicks.
• Adds a NPC link to the buildings site if you have enough resources.
• Adds a “Send as much resources as possible” to the merchant.
• Displays the missing resources for trading with the NPC merchant.
• Works also in combination with ‘Travian 3 Beyond’.

Using instructions:

Once you have installed the script and open a Travian site it will automatically go to your profile site
to extract your tribe. This only happens once. Please check, if your tribe is chosen right.
If not you may choose right one - and you’re done.
From now on each time you open the NPC merchant site you get a list of the troops available for your tribe.
The number in brackets shows the number of units you can build with your resources.
Simply click on the name of the unit and the amounts are automatically entered.
If you want to change all your resources to one click on the name of it - that’s it!
Buildings: In case you want to upgrade a building and you would have enough resources after trading with the NPC merchant a link is available to go straight to the NPC merchant site. The necessary amounts are automatically entered.
If you don’t have enough resources the missing amount is shown.
Merchant: You can click on “max” and as much resources as possible can be sent. There is no more calculation necessary.
