A couple of classes for decorating diagram elements.

Functions

getarrowpath(arrowtopath, selfpos, var1, ...)

Classes

Arrow([pos, size, angle, constriction, sense])	Arrow for Feynman diagram lines
FreeArrow([length, size, angle, ...])	Arrow not attached to any line in a diagram.
Label(text[, pos, x, y, size, halign, valign])	General label, unattached to any diagram elements
LineLabel(line, text[, pos, displace, ...])	Label for Feynman diagram lines
ParallelArrow(line[, pos, displace, length, ...])	Arrow running parallel to a line, for momenta, helicities etc.
PointLabel(point, text[, displace, angle, ...])	Label attached to points on the diagram
