OpenProj: good software, but needs documentation

OpenProj 1.0 was recently released by Projity, which offers a related commercial product called Project-On-Demand. OpenProj is written in Java and licensed under CPAL 1.0, and versions for Windows, Mac OS/X, and Linux can be downloaded from SourceForge.net.

OpenProj -- designed as a replacement for MS Project -- can produce all the graphic reports you're likely to need: Gantt, RBS, WBS, and Network Diagram (PERT) charts, Histograms, Resource Usage, Task Usage graphs, and even a project report.
