Go to these pages for the NFS environment. The sandboxing README is also pre-AFS.
The Development User Guide and System Administrators Guide have more than you want to know about ODE. They also cover the versioning part of ODE, called b-tools, that we were using and are getting rid of in favor of CVS.
The man pages are in /projects/spin/ode/man (add that to your MANPATH).
The ODE tools are included in the build tree. For a stable binary directory, add /afs/cs/project/spin/build/latest/export/alpha/bin to your path. When modifying the tools, you will want to instead put the bin dir from your sandbox export tree on the path.
