versioncontrol_cvs 6.x-1.0-rc1

Companion release to versioncontrol 6.x-1.0-rc1.
Improvements compared to the last beta:

• Still works, due to adapting to API changes.
• Support for release node integration (creating tarballs, and stuff) by implementing a couple of previously missing (optional) API functions.
• Avoid excessively wide tables by cutting off ":pserver:[user]:[password]" from the Root column in the admin repository overview.

In that vein, the CVS backend continues to be the most complete VCS backend to date. Which is a shame, because all other version control systems are way cooler than CVS. Who wants to challenge the CVS backend? C'mon, you can do it!
