DCVS Main Features

DCVS is the CVS based versions control system for software development across physically distributed sites.

It extends the programs CVS and CVSup with functionality to distribute CVS repositories with local lines of development and automatically handles synchronization of the distributed repositories in the background.

DCVS enables globally distributed developer teams to efficiently and securely collaborate on one component of one software product.

The DCVS concept of unique association of development lines prevents collisions and thus data loss.

Advantages of DCVS

DCVS is based on CVS and therefore benefits from all advantages of CVS:
- CVS is stable
- CVS is approved
- all of CVS's strengths and weaknesses are known
Thus, integrating DCVS in your development environment poses no unpredictable risks.

CVS and DCVS are
- integrated in various IDEs and GUIs
- available on almost all development platforms
CVS and DCVS
- use the security infrastructure of their operating system
- use cryptographic hash for access control through application of SSH.
- provide a simple and intuitive user interface
and almost anywhere
- commercial support for CVS is available
The Migration from CVS to DCVS requires minimum efforts
- The migration path from CVS to DCVS ist very simple
- Training is obsolete, as experienced CVS users can also handle DCVS.
Snapshots and Change Sets provide better support for release engineering and process management
Here you can read why the use of snapshots and change sets is particularly advantageous for the configuration manangement in multi-site software development scenarios.

The Unix manual page, section 1 user command dcvs contains a paragraph about the use of change sets and snapshots in dcvs. Here you find the description of the regular use cases.
Simple and quick installation
Even non-CVS-users can easily and quickly install DCVS. DCVS installation on three sites in 30 minutes describes step by step how you have to proceed.
DCVS is an open source project
The DCVS code is freely distributable under the GNU and BSD style licenses. Thus, acquiring DCVS is free of charge and licence bureaucracy.
