VCS

VCS stands for Version Control System (see Wikipedia).

The predominant VCS as of 2022 is Git, which is open-source and distributed, though it is showing its weaknesses and we are looking into finding or creating something better. Pijul appears to be a strong contender, though it is as yet very niche (there's not even a Wikipedia page for it!).

Older popular VCS software includes:

• CVS: centralized control
• Subversion (SVN): widely used in the late 1990s and early 200Xs; centralized control
• Microsoft Visual SourceSafe (VSS): proprietary; centralized control
