sys::get_version() -> tuple>

Return the server version as a tuple.

The major and minor elements contain the major and the minor components of the version; stage is an enumeration value containing one of 'dev', 'alpha', 'beta', 'rc' or 'final'; stage_no is the stage sequence number (e.g. 2 in an alpha 2 release); and local contains an arbitrary array of local version identifiers.
