NOSPUR _ _ _ _ _ _ _ _ _ _ _ _ declaration
The nospur declaration prevents the trace calculation over the given line identifiers in high-energy physics calculations.
nospur<line-id>{,<line-id>}*
<line-id> is a scalar identifier that will be used as a line identifier.
vector a1,b1,c1; g(line1,a1,b1)*g(line2,b1,c1); A1.B1*B1.C1 nospur line2; g(line1,a1,b1)*g(line2,b1,c1); A1.B1*G(LINE2,B1,C1)
Nospur declarations can be removed by making the declaration spur.
