Historical documentation.

On 2013-February-25, the Crossfire project was moved or migrated to the new SourceForge platform. This was required for all projects hosted at SourceForge. In addition to new features and a modified website & interface - the location for the Subversion (SVN) code repository was moved to a new server location - hence the new URL to access it. Gridarta was moved 2013-May-23.

The old repository (url: https://sourceforge.net/p/crossfire/code/HEAD/tree/) is read-only now.
