The first line of a LINK definition.

The linkname must be unique within the map, and must not contain spaces. The only place it currently appears is in the small title-bar of a popup graph if you specify an OVERLIBGRAPH without an OVERLIBCAPTION, however.

There is one special link name, 'DEFAULT', which allows for the setting of defaults. All links that are defined after this one in the configuration file will use the parameters of this link as a starting point. For this reason, it is best to define the DEFAULT link at the top of the configuration file, if you intend to use it.
