Version 1277 was commited by markb on 2009-10-15 09:49:23 +0100 (Thu, 15 Oct 2009) Improve handling of arc headings. We now write curve data that conveys an arc's final heading - the format is fairly well understood but if this causes any breakage use the temporary option --no-arc-curves to disable the arc data. Added --adjust-turn-headings option that, wherever possible, ensures that turns off to side roads change heading sufficiently so that the GPS believes that a turn is required rather than a fork. This also avoids spurious instructions to "keep right/left" when the road doesn't actually fork. Added --report-similar-arcs option that will issue a warning if more than one arc exists between two nodes and the arcs follow similar (hopefully, identical) paths.
