Should say "checkpoint".

[David Jones]

This sentence: "Commits serve as anchor points where individual files or an entire project can be safely reverted to when necessary." (3rd para of "Background") should use "checkpoint" instead of "anchor point" because I think that term is more standard among software practitioner, and more likely to invoke the correct mental image among scientists. So perhaps:

"Commits serve as checkpoints; individual files or entire project can be reverted to any particular checkpoint, thus also serving one of the purposes of backups".

[Karthik Ram]

My rationale for using anchor point was because I was going for a rock climbing analogy. But I'll change to it checkpoint to avoid adding more confusing terms.
