Looking for meaning of no-gs-load-fonts

[Francisco Vila]

Hello. LM 3.6 Alternative methods of mixing text and music ->
Inserting LilyPond output into other programs
says

"To produce a useful ‘EPS’ file, use

    lilypond -dbackend=eps -dno-gs-load-fonts -dinclude-eps-fonts   myfile.ly
"

I am trying to understand what -dno-gs-load-fonts does, and what's the
foundation of these options.  But for my surprise

  git grep no-gs-load-fonts

gives no results apart from this page of Docs, whereas a search for
"include-eps-fonts" does find occurrences in make/, scm/ and scripts/.

Is it an obsolete option?
