Here's a link where the differences between several 12-tone notation
systems are shown and the system of J.M. HAuer is being explained:

Werner:
Hauer's invention is the *second* system in the image; the lines
represent the black keys on a piano keyboard.
Neil:
The custom stave can be created by overriding StaffSymbol #'line-positions,
then it's just a matter of mapping the notes to the correct positions with
a custom layout function (via staffLineLayoutFunction).
It seems to me the only part which LilyPond doesn't support is the special
leger lines below the stave: though the middle C superficially looks like a
G, it's positioned as if it were an E, but with the first leger missing (so
the leger lines continue the line-positioning pattern outside the stave).
