Then another possibility is what is referred to in
http://lists.gnu.org/archive/html/lilypond-user/2018-06/msg00535.html
which is for making standalone files which can be compiled together
as one unit to make a book of parts. But I don't see the usefulness
of that for saving compilation time when the separate files don't
consist of individual works. Surely it's easier to just protect the
includes by using % in front of them when you don't want them compiled.

%% This is the main file
%% Stuff that needs to be defined everywhere:

LP source lines here

% include "parta.ily"
% include "partb.ily"
 include "partc.ily"
% include "partd.ily"
% include "parte.ily"
% include "partf.ily"

%% Probably some \score command would be defined here

\score { … }

%% End of mail file

That file would compile just the section C. What the June 2018 person
seemed to want was to be able to type

lilypond partc.ily

and have that produce a score of just that part. That requires
thinking carefully about how the "LP source lines here" gets
included in this case.

Cheers,
David.
