Walks all open fonts and looks for a component that is a reference of another component. Is dumb and assumes that there is only one component the reference. Good for quickly cleaning up UFOs before importing into FontLab, where this sort of thing isn't allowed.

fonts = AllFonts()
for font in fonts:
    for g in font:
        if len(g.components) != 0:
    
            for c in g.components:
                b = font[c.baseGlyph]
                if len(b.components) != 0:
                    e = b.components[0]
                    eb = e.baseGlyph
                    bx, by = c.offset
                    ex, ey = e.offset
                    g.removeComponent(c)
                    nx = ex + bx
                    ny = ey + by
                    g.appendComponent(eb, (nx, ny))
                    g.mark = (1,0,0,1)
