Here is demonstrated a preliminary support of Gregorian Scripts:

ictus, circulus, semicirculus, accentus, episem.

"}

%{

TODO: augmentum.  Syntax: either as bracket (\augmentumInitium,
\augmentumFinis), or as head prefix with subsequently collecting all
dots and putting them behind the ligature in a vertical row.
Counterexample to the second approach: Graduale Triplex, tempus per
annum, hebdomada septima, alleluia (page 280).

FIXME: horizontal spacing (ragged right mode).

FIXME: padding/minimum-distance is fragile.

FIXME: episem stops one notehead too early.
