Widelands

Implemented in revision 3543.

The attached patch implements both default target quantities (defined in
the conf-files of ware types) and a configuration dialog that lets the user
play with other values than the defaults.
File Added: target_quantity-1.diff

Current SVN, build13rc and build13rc2 (released soon) has a simple form of
on-demand production. Buildings will produce what is needed. This will
eventually be improved in steps. The first step will be to define default
target quantities that should be kept in storage of each ware type. The
second step will be to add a user interface to allow changing those target
quantities in an economy.

For the first step, the conf-file of each tribe will have a section that
looks something like this:

[default target quantities]
beer=3
pick=3

hi! for me this is the most wanted feature in the game.

On-demand production should be implemented to choose what is produced (for
example in the metalworks). Read about it here:
