[Freeciv-Dev] OR Requirements for Buildings

[Benedict Adamson <badamson@xxxxxxxxxxx>]

Using the new requirements style for buildings, how do I express that 
any one of several requirements is needed for a building, rather than 
requiring all the requirements in a list are necessary? Or is that not 
now possible?
The Ancients rule-set has a Fish Market improvement, which could be 
built in a city adjacent to an Ocean tile or adjacent to a river tile.
This was done by having a spec_gate = "River" and a terr_gate = "Ocean"
