For a very long time, there have been no official release of LDraw parts, so
many useful unofficial parts have accumulated on LDraw Parts Tracker. While
LDraw Parts Tracker provides a way to download them
all(http://www.ldraw.org/modules.php?op=modload&name=News&file=article&sid=14&mode=thread&order=1&thold=0)
there is no simple solution for LeoCAD users. So I have prepared a parts pack
for LeoCAD that includes all unofficial parts available as of March 20, 2008.
This parts pack is available here, with installation instructions: http://philohome.com/leoupd/leoupd.htm
