NVO Software
An NVO software library is available via a CVS server. The NVO uses an anonymous CVS server so that anyone can check out the most recent version of the software with read-only access.
Checking out code anonymously via the web
See http://www.us-vo.org/viewcvs/ for the web interface to the NVO CVS Repository. You can browse the file hierarchy by picking directories (which have slashes after them, e.g. , VOTable/ ). If you pick a file, you will see the revision history for that file. Selecting a revision number will display that revision of the file. There is a link at each revision to display differences between that revision and the previous one, and a form at the bottom of the page that allows you to display diffs between arbitrary revisions.
Checking out code anonymously via command line
You can also check out the code via command line. See this page for instructions.
