In CG 2.2, under “Where to get lily-git" it reads:
If you are using LilyDev (see LilyDev) then lily-git should already
be installed and ready to run.
But it seems that this is not the case with LilyDev 4. At least not
when I tried it today. Not a big problem since as it goes on to say:
If this is not the case you can easily turn it on by adding the
following line in ~/.bashrc:
# add lily-git to the PATH
PATH=$LILYPOND_GIT/scripts/auxiliar:"${PATH}"
This worked fine, but it would be better not to have to take this
extra step, for those using lily-git.tcl
