vrsion = "2.18.0"
\version "2.18.0"
at least allows you to see they're the same at a glance.
Then embed \vrsion in your tagline.
But there's a category error here, isn't there? The lilypond-version
is a property of the program and hence the run. So, like many, I have
\concat { "LilyPond version " $(lilypond-version) } embedded in my
typical tagline. The PDFs bearing that tagline were all run by that
lilypond-version.
OTOH the \version is a property of each individual file. A run might
include many files written in the syntax of different versions.
Understandably, files like (a trivial example)
%% Letter-landscape.ily
\version "2.18.0"
\paper {
#(set-paper-size "letter" 'landscape)
}
don't get put through convert-ly very often.
So it's moot what an overall printed \version should be.
Cheers,
David.
