// HEADROCK HAM 3.4: Dynamic Roaming Restrictions XMLization
|
||||
//
|
||||
// This is a new part of the Dynamic Roaming Restrictions system. It reads in
|
||||
// data about sectors to "un-restrict", and the towns that must be liberated
|
||||
// for them to be unrestricted. There can be several unrestriction conditions
|
||||
// for each sector, and only one of the conditions must be true for the sector
|
||||
// to become allowed.
