2.13.3 docs emacs mode documentation AU 2.2.1 out of date?

[Paul Scott]

Hi,

I'm resurrecting a laptop whose hard drive died.  I'm trying to set up 
Emacs lilypond-mode.

AU 2.2.1 tells me to do a 'make install' in the elisp directory.  I 
don't see a makefile and 'make install' doesn't find an install target 
rule.  Am I missing something or are the docs behind?

Thanks,

Paul Scott
