# simple example

# stock name:quantity
euro:10
#
# process name:(need1:quantity1;need2:quantity2;[...]):(result1:quantity1;result2:quantity2;[...]):delay
#
buy_materiel:(euro:8):(materiel:1):10
build_product:(materiel:1):(product:1):30
delivery:(product:1):(client_content:1):20

# optimize time for no process possible (eating stock, produce all possible),
# or maximize some products over a long delay
# optimize:(time|stock1;time|stock2;...)

optimize:(time;client_content)
