Want to try the latest and greatest? '''Version 0.6.0 (9/18/2006)''' is
a major overhaul that adds a point-and-click, drag-and-drop '''map
builder''', not to mention support for paths (with a color chooser!).
In addition, performance of the rendered maps is improved compared to
previous versions. However, because installation is noticeably trickier
than before, this is '''not recommended for all users'''. In fact,
development may continue along two lines: an easy to install "light"
version (that is, the 0.5 series) and a more feature-packed
"heavyweight" version (the 0.6 series). Anyway, if you're interested,
see
