This might be a great program, but the installation information is so outdated its almost impossible to deal with.
The Fedora install help tells you how to install Fedora 1 - not the program.
PostgreSQL itself makes MySQL look like an easy install. The path to python scripts in the setup defaults to a non-standard location, and even when it points to the right place it won't run.
The program might actually be great, and I could surely use a good document manager in linux BUT....
The best way to run this program might be to get a Windows Port and run it in a virtual machine. Its really that bad.
