Re: jazz articulations

This is embedded postscript code.  You can find a reference for
postscript commands at
http://www-cdf.fnal.gov/offline/PostScript/PLRM2.pdf.  The rcurveto
function is described on page 469.

The ps function rcurveto draws a bezier curve from the current point to
the third point in the argument list, using the first two points as
control points, with all coordinates expressed as relative distances
from the current point.  Thus,
"0 -1 -0.7 -1.8 -1.2 -2 rcurveto"  will draw a bezier curve from the
current position to a point that is -1.2 units in the x direction and -2
units in the y direction from the current position, using the _relative_
points 0,-1 and -0.7,-1.8 as control points along the way.

In lilypond, (almost?) all units are defined in terms of the staff
spacing, so 1.0 would be one staff space.

Hope this helps.
