Martin, All,

OK, that's good. :-) You could have said it more explicitly in the
commit log, after a three-dash line:

    package/nodejs: Define NPM command for other packages to use

    Other nodejs-related packages will need to call npm with the same
    set of arguments as is currently used by the nodejs package itself.

    To avoid duplicating this code, set the NPM variable so those
    packages can re-use it.

    Signed-off-by: you

    ---
    Note: currently, this is only used in the nodejs package itself, but I
    plan on swnding new nodejs-related packages that will use this, like
    nodejs' serialport or pm2 packages which I have tested successfully
    using this $(NPM).

(Or something similar, choose your own words if mines are way off! ;-) )

To be noted: whatever gets added after a three-dahs line is omitted by
git when the patch is applied by the maintainer, so you can basically
write whatever you see fit in there.

Thanks for the explanations!

Regards,
Yann E. MORIN.
