/* Capabilities: Author: Mitch Davis (mjd@alphalink.com.au)
 *
 * Here's the string a client and server trade to find out if they can talk
 * to each other, and using which protocol version.  The string is a comma-
 * separated list of words, where each word indicates a capability that
 * this version of Freeciv understands.  If a capability word is mandatory,
 * it should start with a "+".
 *
 * eg, #define CAPABILITY "+1.6, MapScroll, +AutoSettlers"
 *
 * Note that there are separate c_capability and s_capability char[]'s in
 * the client and server, which are valid if the client has been accepted
 * by the server.  Client and server software can test these strings for
 * a capability by calling the has_capability fn in capability.c.
 *
 * Known bug:  There is only one c_capability in the server, whereas there
 * should actually be one per connection.  This is being worked on.
 *
 * A note to whoever increments the capability string for a new release:
 * It is your responsibility to search the Freeciv code, and look for places
 * where people are using has_capability.  If you're taking a capability out
 * of the string, because now every client and server supports it, then
 * you should take out the if(has_capability( code so that this code is
 * always executed.
