Lepido is an archived project at Eclipse to build an opensource IDE for Cocoon. It was archived due to lack of development but an early release can still be taken from the archive and has useful sitemap navigation features.
As Eclipse currently doesn't provide a wiki to its project, the Cocoon team was kind enough to allow Lepido to make use of its wiki.
This currently runs with Eclipse 3.0.x and seems to run fine in Eclipse 3.1.
