We relocated the Paxtools sources to
Github git repository.
All the Mercurial SCM repositories here are now read-only.
We also plan to make a new biopax.org website, to
deploy project artifacts to OSSRH and Maven Central,
have a new location for downloads and documentation, etc.
Watch for more news.
The BioPAX Validator sources were moved
FROM http://hg.code.sf.net/p/biopax/validator (Mercurial repository; browsable at https://sourceforge.net/p/biopax/validator/ci/default/tree/; - read-only access from now on)
TO https://github.com/BioPAX/validator (GitHub, Git repository)
It'll take some time to update existing BioPAX wiki and post a message about this move somewhere on BioPAX.org, sf.net/p/biopax, etc.
We are managing BioPAX sources using Mercurial (http://mercurial.selenic.com). The CVS is deprecated.
