LilyPond manual - version?

[Francois Pinard]

Hello, Han-Wen and LilyPond friends.

I have two printed copies of the LilyPond manual.  They are not similar,
one has four more pages than the other, but both title pages say the
copyright is for 1999-2002.  I do not quickly find in either which version
of LilyPond they document.  Is there any special place to look at? [1]

Would not it be a good idea to identify the version prominently, even on
the title page?  Maybe also a date -- either full English or ISO 8601.

--------------------
[1] Another question is: suppose I had the version numbers.  Could I then
easily retrieve past LilyPond distributions, so to `diff' the manuals in
magnetic form?
