Wrong. If you do a diff between two releases of GCC (say, 4.4.3 and
4.4.4) the result is literally hundreds of thousands of lines long
(even between minor, bug-fix-only releases), so unusable for a human.
In contrast, if you browse the version control log, you get a summary,
with explanations and bug numbers, of the changes; then you can narrow
your "diff" to the commits that you are interested in.

CVS would not even help do that because CVS, being rubbish, has per-
file histories as opposed to per-project history.

What you say might be true in a few particular cases with severe
restrictions such as SLOC count < 10_000 and developer_count < 5. In
the general case, a proper version control system is, quite simply,
vital.

Note: I do not even bother to create tarballs of the software that I
publish; my version control system does that for me automatically, see
http://www.ada-france.org:8081.
