Multiple versions of Lilypond?

[Kira Garvie]

Hi all,
I saw this referenced in the Frescobaldi manual, but is it possible to have
multiple versions of Lilypond installed on my computer at once? Many of you
know I have to use version 2.16.2 for my work (don't ask me why, I honestly
don't know), but I would like to use a more recent version for some other
engraving jobs. And can I use an older version of Frescobaldi with a newer
version of Lilypond?
Thank you!
Best,
Kira
