Servers Manager Dialog
Used to select and manage WMS servers.
Opens when you click the Servers (selection) button in the WMS Map Editor dialog.
When the Map Editor opens a dialog for the first time, it retrieves the value of the configuration variable MS_WMS_SERVERS to get the name of the file that contains the list of servers. If the file does not exist when the Map Editor is invoked, the Map Editor creates it by copying the file specified by MS_WMS_SERVERS_SEED.
