cvs 2:1.12.13+real-5 (amd64 binary) in ubuntu oneiric

 CVS is a version control system, which allows you to keep old versions
 of files (usually source code), keep a log of who, when, and why
 changes occurred, etc., like RCS or SCCS. It handles multiple
 developers, multiple directories, triggers to enable/log/control
 various operations, and can work over a wide area network. The
 following tasks are not included; they can be done in conjunction with
 CVS but will tend to require some script-writing and software other
 than CVS: bug-tracking, build management (that is, make and make-like
 tools), and automated testing.
 .
 And a whole lot more. See the manual for more information.
 This package includes the client and server both, but pserver has been
 deprecated in favour of ssh, so no repositories or inetd server entries
 are created automatically any more.
 .
 GNU CVS, with the patches from here applied, is used (in this patched
 version) heavily by the MirOS Project, internally, and to maintain the
 MirOS BSD, MirPorts Framework, and other subprojects', as well as
 hosted projects, such as FWCF, source code and associated other works.
 .
 This version also contains many patches originating from Debian.
